MyTouch 3G 1.2 - No Service

I have a MyTouch 3G w/3.5mm headphone jack that I bought from Craigslist. I just use T-Mobile ToGo Prepaid, so I had to get the phone unlocked (got unlock code through T-Mobile for free) and I used my mom's AT&T SIM Card to activate the phone.
After doing that with stock firmware, my T-Mobile SIM card still won't work in the phone. I got zero bars and with a small "X". I thought maybe T-Mobile purposely blocked non data plan SIM cards in their stock ROM, so I rooted and installed Cyanogenmod 6 RC2. Everything went fine with the rooting and upgrade, but I'm still having the same problem with my T-Mobile SIM. It always says "No Service". If I try to dial a number, I get "Mobile network not available." In Settings->Mobile network settings->Network Operators, it shows both AT&T and T-Mobile as available networks. If I touch T-Mobile, I get "Unable to connect to this network at this time. Please try again later". The strange thing, is everything works fine with an AT&T SIM card! I'm at a loss to figure this out. Are these symptoms of a blacklisted IMEI? Or do these symptoms indicate something else?
UPDATE: Talked to T-Mobile chat, IMEI is NOT blocked which is good, but it's still not working.

had the same issue...I used my friend's AT&T sim with data plan to sign-in to google. I had to enter AT&T APN settings and choose AT&T network in the menu.
Everything went well and I put my prepaid togo sim card. Got no service message and no bars. I went then to menu-settings-wireless controls-mobile neworks-network operators. It scanned networks for a minute and found t-mobile which I chose. Right after that it connected to network and I was able to make my first call from prepaid card

Unfortunately, that doesn't work on mine. When I touch T-Mobile, I get "Unable to connect to this network at this time. Please try again later."

are you sure your t-mobile sim card still work fine? i did research quite a bit this issue yesterday and many people confirmed that prepaid card works fine for them. check your network settings again and reset them to default

Yeah, it's the SIM card I use in my iPhone daily. My wife's SIM doesn't work in it either. I've reset everything to defaults, wiped everything, and even installed Cynanogenmod with no luck.

sorry to hear that...maybe you should try to call t-mobile or visit a store

I did talk to T-Mobile, but they only suggested a full wipe (hard reset) which didn't work. I guess it's probably broken, and since I bought it second-hand, not covered under warranty. It's unlocked so I guess I could try to recoup my losses by selling it to someone w/AT&T.

S7 Edge Duos data connectivity problems

Hi all,
I have the dual sim S7 SM-G935FD running the XSP firmware. Rooted with the microSD Mod on Sim 2. It's being used in the USA at the moment. Sim 1 is AT&T and Sim 2 is T-Mobile. Both are USA sim cards. Everything goes through Sim 1 AT&T - Voice, Text and Data. Sim 2 is just for receiving calls only. Sim 1 is set at LTE/3G/2G and Sim 2 is 2G only.
Since day one I have this connectivity issue pertaining to data connection.
When Sim 2 gets a weak signal and eventually drops out, data connection on Sim 1 remains - everything works. However, when Sim 2 is picking up signal again, the data connection on Sim 1 drops out.
When this happens, the pull down notification will display that the data connection is on Sim 2 - as if the phone switches the data connection from Sim 1 to Sim 2 by itself. However, if I go to the Sim Manager, it will show that the data connection is still on Sim 1 like it originally was. At this point, the phone has no data. And yes, the phone is displaying conflicting information. Notification says Data is on Sim 2 but Sim Manager says Data is on Sim 1.
To fix this, I have to use the Sim Manager, select Sim 2 for Data. Wait a few minutes. Then, choose Sim 1 for Data again, then everything comes back normal. Data connects.
This is quite annoying in a poor reception area.
Troubleshooting steps that I have tried but they do not fix the problem-
Flash stock firmware no root
Use a different stock firmware - XEU
2 sim cards only with no microSD card on the back of Sim 2
Choose 3G/2G only for Sim 1 and 2G for Sim 2
Swapping Sim 1 and Sim 2
If I disable Sim 2 the problem goes away, but of course, what's the point of dual sim then?
I also have a S6 Edge+ Duos SM-G9287 but it does not have this problem.
Any ideas? Thanks.

Just wanted to add that I am experiencing this as well.

Man this is getting unbearable. Is there a specific forum for the FD devices? I'm thinking I might just return this phone while I still can.

Wow I was going to put something on boards as well with literally the exact same setup in USA. It gets way annoying when tmobile gets weak and switches even though I have it set on sim 1 data. I really hope there is a fix or else I might make the switch to htc10 (if they even get a dual sim) and keep my fingers crossed it works better. My S6 duos works better than this but I don't have additional memory with hybrid SD sim card on s7.

FYI -
I have been running XSG firmware. I just upgraded from APC8 to APD1 and the problem still remains.
Just trying to save some time for those of you who thinks upgrading will resolve the issue... it will not.
It is amazing how the S6 Edge+ Duos does not have this problem. Things went backwards for Samsung.

No problems here though mine is the G9250 dual sim version (HK).

G9250 is s6 edge is it not? We are on g935FD. It seems like I can never find the elusive perfect dual sim! Always some kind of bug! Might be heading back to my Xperia z5 premium. Can you guys confirm that it's wifi causing it? Seems like whenever I come off of a wifi network it never picks mobile data back up.

That seems like part of the problem too..as soon as wifi loses connection then it switches and then no more data

Has anyone fixed this? I have tried to flash a couple different modem firmwares to no avail. The T-mobile one won't flash as it uses a snapdragon chipset.

Mine was doing fine until I did a firmware update and now the data connection problem appeared. I was on a B6 firmware with a B9 modem on a AFG CSC so I will try to go back to this and report back whether the issue resolves. Any firmware starting D1 (tried D3, D6 and D8) causes the data connection lost issue. Even just going back to a B9 modem with the D8 firmware didn't help. What a pain in the rear...

Follow up to my previous post:
Officially, G935FD is a piece of crap. Tried every combination of modem/AP to get this work but no luck. Resorted to single sim mode for now.

I have this same issue. the only way it works is to manually select one sim in use at a time. I just removed the second sim and added a micro sd card for now.

Did you update your firmware to a different CSC? That's when my issues started (went from AFG to BTU and even after going back the problem wasn't fixed)
What is your original CSC?

Mine didn't work out of the box with stock firmware. I have since upgraded the stock firmware but haven't tried using two SIMs with the latest update. Maybe I'll test it over the weekend.

+1 on this bug existing for me since day one. I have been sticking it out and staying with dual sim as I don't have any other option. Kinda wishing I had just returned it... I have gone through hell trying to talk with people in India (where the phone is apparently from) about just getting the bug's existence up the chain. If only we could get a dev to take a look at our logs so I can have a reason to just root the damn thing already. Has anyone tried maybe flashing the sim manager apk from the s6 edge? Is there even a sim manager apk?

I have exact same problem with S6 edge+ dual sims. SM-G9287. Problem started since marshmallow updated. Didn't have this problem before under old android version. Has anybody found any fix yet? Right now, If I disable one of the sim, then it seems ok, but I need both sim to be on to receive call on either number.
My phone was stock firmware. Problem seems to be with Marshmallow 6.0.1 , not because of custom firmware.

Kind of same problem here, but it happens only since I received the update to APD1.
I live on a border zone, so I have to force my LTE sim card to its own network. The second SIM is only on 2G.
When the phone loses its own network, SIM with LTE completely disappears, everything is moved to SIM 2G and of course I lose network. The problem is that the SIM with LTE is not seen anymore, even if I go back where the signal is, and the "mobile networks" option disappears in the Settings. I cannot do anything else the reboot the phone to see the SIM again.
Ciao Marina

I have similar issues with my s7 duos not the edge model. Sim1 tmobile, sim2 at&t. Sim2 seems to be the issue for me. Cell quality at my house is not great. I also have a xperia z5 premium dual that has similar problems mainly with lte. The samsung does hold lte signal but the bars are misleading. But the samsung, I woke up this morning and sim2 was offline no calls or text or data. Call quality with sim2 isnt as good either. I blame cell signal on that since the sony has similar issues. But I have seen it with sim1 set to calls and texts and sim2 for data the pull down says sim1 even though sim manager says sim2 is data. Wtf right? Disabling sim2 and reenabling gets it back working again but what happens when the phone does this is you lose data since sim1 data would be gsm only. The common theme is sim2? Also seems signal quality is a big factor. My CSC code is ECT which is Nigeria. I have not changed firmware yet other than the APD1 update. Ironically my xperia z5 dual didnt have these issues at all with lollipop the problems started with marshmallow. I am in the US by the way.

Temporary fix?
Looks like I accidentally ran into a temporary fix, that's working for me for the last few days. I'm on Vodafone for SIM1 and T-Mobile for SIM2, EU&US.
When I restart the phone and set SIM1 for data on LTE/3G/2G it connects, but looses the connection after a while and defaults to SIM2 (with no data). No BT, no WIFI, no data icon anywhere the screen.
When this happened, I ejected the SIM card holder and pushed it back in 2 seconds. Suddenly SIM1 was trying again to connect and the 4G icon appeared. At his point I turned on WIFI.
The weird stage: WIFI on, 4G icon flashing every 5secs – but it's working as it should. If I loose reception, it does not switch cards. Actually never switches card if I don't want to. I can live with the flashing 4G until we have an official fix.
Let me know if it works for you guys!

Im learning that mine is a lot more stable if I set everything to the same sim and not split up talk/text on sim1 and data only on sim2 like I was doing. Not sure if this is placebo for now but I have everything set to sim2 and so far so good with no drops.

G935U firmware with Verizon MVNO

Hi guys,
I bought the unlocked firmware phone back in December 2016. The phone is great, the problem is I am using EcoMobile MVNO. It's refusing to recognize the network with the MVNO's sim card. I've spent hours on the phone with them and they claim all is OK on their (and Verizon's) end.
The phone sort of works, so I've just been grinning and bearing it so far. Using 4G switcher, I can put it in CDMA only mode, in which case it connects to '123456' and I can receive and make calls, and receive texts, but have no internet. If I put it in full LTE/GSM/CDMA auto mode, it connects to LTE, so I have internet, but it claims I'm not connected to Verizon network and in fact it's not available. So in this mode I can't receive calls or texts. Can't send texts under any mode. I've done a full factory reset at the MVNO's behest, of course that did nothing. The phone seems to connect fine to Verizon's network if I borrow someone elses's Verizon sim. My MVNO sim also works in my wife's iPhone5 without a problem. So it really seems to come down to the firmware on the phone. I'm holding out against hope that when Nougat comes to the G935U firmware, this problem is magically solved... but just in case decided to post here.
Please help, any ideas would be appreciated.

Flash the vzw firmware or go through the steps for the hybrid rom with vzw modems implemented.

Thanks. I was really hoping for something less intrusive, maybe some CSC edit fix, or some such.

Welp, the 7.0 update is here, and it didn't fix my issue, in fact now I can't even get LTE data as I used to get. :crying:

So I had this issue when I first got the nougat update. When I got my S7 I put in my brothers sim card to made sure it worked on Verizon cause i was buying it from someome and anyway I activated my straight talk verizon SIM and everything was great until I got the update and my service was weird and I didn't know what to do and then it dawned on me, I put in an actual verizon SIM card, doesn't need to be active let it register and then put your SIM back in and everything was great! Hope this helps...

Switched to TotalWireless, phone works now. They first sent me a SIM which didn't work, then had to send a different, post-paid one.
I now suspect if ECO also sent me a postpaid based SIM it would start working. Things are always way too complicated when Verizon is involved.

I'm tempted to try this as I'm having the same problem with my 935U and Xfinity Mobile (Verizon MVNO) SIM, instead of connecting to the Verizon network, it connects to network 123456. I did load the 935V firmware, which worked fine, but I'd prefer to return to the U firmware if this would work. Is this still working for you, and if so, do you just need to put the regular verizon sim in once and from then on the MVNO sim will work, and continue to work including after a reboot?

I put in a Verizon SIM in it once and that was after the nougat update. But every time the phone restarts, I have to make a phone call for it to connect to the service or it will just stay stuck in "searching for service" but once the phone call connects, I hang up and everything works as it should.

Thanks, strange problem. I'll probably just stick with the 935V firmware for now as that's working fine (just have the Verizon bloat and failing the hotspot check). I also have a dialog going with Samsung support to see if they're aware of the problem and have a fix.

Unable to register phone on T-Mobile network

I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.

Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.

Unlocked S8 failed to register Red Pocket SIM on Verizon after reboot

First thing first, I have sent the unlocked S8 (bought unlocked directly from Samsung) back to repair center for the issue. The phone was returned to me, claimed to be repaired, with the same issue. While I submitted another ticket to send it back again, I believe the devs here may have better solutions than the incompetent technicians at Samsung repair center. I need help!
Description of Issue
Before routine phone reboot
• AT&T compatible SIM (Cricket) worked on the S8.
• Verizon compatible SIM (Red Pocket) worked on the S8.
After routine phone reboot
• AT&T compatible SIM still worked on the S8.
• Verizon compatible SIM couldn’t register on Verizon’s network on the S8. However, the SIM could register on Verizon and make phone calls on another two phones.
• Verizon SIM worked on the S8.
I was instructed by a Samsung technician through chat to
a) do a network reset
b) enter safe mode
c) do a factory reset
None of the above worked. No setting (APN or whatnot) is required for the AT&T compatible or Verizon compatible SIM to work. In short, the Verizon compatible SIM is working properly and the S8 is not blacklisted by Verizon. The S8 just doesn’t work with the Verizon compatible SIM after a reboot.
After the repair
I just received the S8 from the repair center from the previous ticket. I inserted the Red Pocket SIM to S8 and the phone still couldn’t register it on Verizon’s network. I inserted the same SIM to another phone and the phone received messages from Red Pocket right away and showed it was on Verizon’s network. In short, the same issue remained.
Even though I'm sending the S8 back to Samsung for repair, given my first repair experience, I don't have much confidence in their technicians in fixing this. Any input is much appreciated!

Did you figure this out? I am having the exact identical issue and ready to go nuts trying to figure it out. Any help would be great!

Unfortunately, I haven't. But I do have updates. I sent the phone back for a second repair. The phone came back with the same problem. No surprise at all. One thing I noticed though, from the service record, the technician replaced a third component (the other two were the same as that of the first service). Not sure if this made a difference, I did see "Verizon Wireless" on the status bar when I turned the phone on with the Red Pocket SIM. This was the first time I saw the "Verizon Wireless" after the reboot. However, while I was turning it on, the S8 mandated a reboot to "get the SIM card ready." And man... that reboot just reverted everything to before.
I was on the phone with a Samsung representative and a supervisor after I discovered the phone was not fixed for the second time. While he promised to make a note to the repair center about my situation, the supervisor said the option of a replacement phone wouldn't kick in until 3 or 4 unsuccessful repairs. Frustrated as I was, I've got no choice but to send it back for a third repair.
Hope you have better luck with yours.

Thanks for the reply. The phone I was having problems with was an S8+. My wife's phone is an s8. I didn't have any problems on Red Pocket CDMA for the first week of service. That was until this morning. Exact same thing on my S8+ and what you describe above. On another forum someone said this is a problem with Samsung devices on Verizon MVNOs.
I just switched both to GSMA for now until I figure out to switch from Red Pocket.

Thanks for sharing, especially on Verizon MVNOs. GSM (Cricket) has no signal at all in many locations around where I live and work. If Samsung still couldn't fix my S8 after a couple more tries or even with a replacement phone, I will have to opt for the Verizon MVNO theory and buy a different phone. Heck, my $40 Moto E4 works just fine on both Cricket and CDMA Red Pocket.

I have the same issue my believe is red pocket does not have LTE/CDMA in their sim they have LTE/2g/3g 2g/3g and 2g only they should have LTE/CDMA instead of LTE/2g/3g to work,

Update:
No. This problem was not fixed by Samsung after three repairs.
I ordered a new Verizon SIM from Red Pocket during the third repair. Samsung didn't replace anything in the third. I received the phone and popped in the new SIM and the phone could register the SIM on Verizon! I even tried a couple of restarts (which caused the problem in the first place) and everything seemed fine. I even blamed myself for bashing Samsung technicians' incompetence. How stupid was I to blame myself and how naive was I to believe Samsung technician had actually delivered...
It's the fourth or fifth day I've been using the phone and the new SIM. The battery died after a long day. When I returned home and charged the phone, the S8 needed to "reconfigure" the SIM, which prompted for an automatic reboot. Voila! The same pesky unable-to-register-on-Verizon issue came right back. The phone is now in the process of a replacement. I honestly don't hold much hope for the replacement that I'm awaiting. Perhaps I should consider selling off the phone or asking Samsung for a refund.

Confirmed s8 doesn't work on the budget Verizon mnvo's
I just switched from the att sim on red pocket to the Verizon sim with no luck. I found a temporary fix. When prompt to restart to configure network, press the power button and go into emergency mode. Then restart from there. May take a couple of tries but the prompt disappeared. Then switch back to regular mode. I was able to use the phone on Verizon but can only get 3g speeds. This all goes away the moment you restart the phone as the moment the confirmation takes it won't recognize the Verizon networks. This is a cheap Verizon service. You can see your options for network mode are lte/3g/2g. Not the typical lte/cdma. Also tried boom mobile, and that sort of worked but my texts would not go out and again no fix. I'm convinced this is purely Verizon restricting needed services that the s8 requires. The att sim works perfectly. Most phones are fine, not the newer Galaxy.

I just switched from the att sim on red pocket to the Verizon sim with no luck. I found a temporary fix. When prompt to restart to configure network, press the power button and go into emergency mode. Then restart from there. May take a couple of tries but the prompt disappeared.

Thanks for the workaround. I'll give a shot when I receive the replacement. Meanwhile, I have been using an unlocked prepaid Verizon Moto E4 and everything works fine. I have 4G with the E4. I can also receive multimedia text. A $40 budget phone works better for my needs than a $700 factory unlocked premium phone. How ironic!

I have the same problem
I have a fully-paid-for Galaxy S8 from a Verizon account with good standing, and service on this particular line is ended. It worked on Redpocket until I took the sim out to insert an SD card. Afterwards it reconfigured the sim and lost network access. The sim works in my iPhone and the original Verizon sim works in the S8 and the phone states its ready to set up a Verizon account.
The third Redpocket support agent I contacted sent me a screenshot listing an error "DISCOUNT_4_ACCESS". He stated that means Verizon is blocking it for some reason but he doesn't have access to the reason. Two Verizon agents couldn't even tell if they were blocking it or not - but as far as they could tell everything was good.
According to an article on Whistleout, Verizon MVNO requirements are that the "phone must be network compatible, financially unencumbered, and not less than 12 months old (though this last policy changes from time to time)" Could our phones be blocked because they were sold less than 12 months ago?

Thanks for sharing this. I bought a Moto E4 around February, a Verizon postpaid (or prepaid?) from Walmart and got it unlocked through eBay. This is the phone I'm using with Red Pocket now. The phone is of course less than 12 months old. One thing to mention is when I asked Red Pocket support to activate a new SIM with the E4, I was told because the phone was Verizon branded (post/prepaid) they could not activate the phone with the SIM. Then I told them I had success before. The rep further said the service would be deactivated once their system detected the phone was Verizon branded. Well, it turned out this rep knew nothing. I ended up using IMEI of another phone to activate the line then inserted the SIM in the E4. And I have been using the E4 ever since without a single issue (network-wise).

Wow, so i wasn't the only one. Had the exact same problem. Ported my number from Red Pocket Verizon to Red Pocket AT&T. Now everything is fine.

When I switch from a Verizon SIM to my Red Pocket-Verizon SIM the phone comes up with "SIM card changed" but the phone receives incoming calls and notifications (wi-fi is off). Unfortunately, the only thing that I can do with the "SIM card changed" message showing is answer phone calls - I cant even turn "Emergency mode" on. Could it be that Red Pocket SIM messes up the configuration? One of the first things Red Pocket support wants to check is if the phone is in CDMA mode, but with the Red Pocket sim inserted modes are limited to LTE/3G/2G. The Verizon SIM gives CDMA options.

With the Verizon SIM in and configured, switch to "Emergency Mode". Replace the Verizon SIM with the Red Pocket SIM without turning the phone off. Turn "Emergency Mode" off. The phone doesn't detect the SIM change, but it shows the ICCID of the Red Pocket SIM and correct phone number. Data works, 4G LTE. Of course, the first power cycle it detects the SIM change and messes up the configuration.

Another update: Received an unlocked S9 (yes, because Samsung is out of unlocked S8 inventory) two days ago. Inserted Red Pocket Verizon... the phone couldn't register the SIM on Verizon at all in my first try. This is the end of my journey with Samsung phones. I hope one day this issue can be addressed and solved.

Am having the same red-pocket/Verizon/S8 problem. Too bad I did not see this first.
I have tried almost everything (barring having a different network Sim Card) to have my phone request me to restart the phone on inserting new sim. It appears the last network is saved somewhere and my unlocked/unbrand S8 does not seem to forget it.
Is there a way where I can force the phone to request a restart if I re-insert the Sim card. Thanks

My understanding is that Galaxy S8s are configured wrong when Red-Pocket (and other Verizon MVNO) SIMs are inserted - they aren't fully set to the Verizon network and if your phone had, for example, and AT&T SIM, the phone stays AT&T branded when a Red-Pocket Verizon SIM is inserted.
The work-around:
1) Insert a Verizon SIM and let it setup everything and reboot when it wants.
2)Turn on "Emergency mode" (Hold down the power button and select "Emergency mode")
3)Insert Red-Rocket SIM
4)Turn "Emergency mode" off
*If you reboot after inserting the Red-Pocket SIM the phone will become wrongly-configured and you'll need to do the work-around again.

Thanks for the update. Yes - if I can only get hold of a non Red-pocket Sim, this can work. Since I don't have Verizon (or any other) Sim card, I was wondering if there is some other workaround to have the phone request me to restart. I suppose I would still need Verizon Sim since it uses that to configure the network.
Looking at another thread - it appears the 'configuration' that Verizon sim card does has to do with CSC codes. My phone is unbranded, so the codes are XAA (Firmware) and XAA (Network). I believe the latter has to be VZW and a Verizon Sim fixes that. Someone who has successfully used the workaround can confirm what codes are being displayed at their end. I am using 'phone info' app. Then maybe we can work to find another workaround ....

My S8 is Verizon branded. It CSC is currently VZW. Under "Service provider SW ver." its VZW/VZW/VZW.
