Unlocked, SM-G900A (ATT) on Tmobile, now what? - Galaxy S 5 Q&A, Help & Troubleshooting

I switched to Tmobile and craigslisted a SM-G900A, got the unlock code from ATT, put it on tmobile.
I want the bloatware gone, for sure.
I've read it's not safe to put a tmobile rom on it, especially the A, so is there any other way to 'optimize' it for a network it wasn't designed for?
We bought my husband an unlocked 3rd gen moto g, and he's been having better network connectivity.
I understand I'm using this phone on a network other than what it was designed for - but hardware wise it should be fine.
What have the developer gods come up with firmware/software wise that can help me?
I'm out of my league here, never had to work cross carrier.
Thanks so much,
Silvia

Is Verizon S5 unlocked? Can it be used on T-Mobile?

Hey guys. Is the Verizon S5 CDMA + GSM?
Is it factory unlocked?
Can it be used on T-mobile with everything working correctly (LTE/4G)?
Thanks

I don't know the answer to your question but I can confirm that the Galaxy S5 that I received from TMobile was in fact LOCKED.
I called the support # and was told that I had to have service and use it for 40 days before it could be unlocked.
I PAID THE FULL PRICE ($720 with tax)!!!
I asked to speak with a supervisor -- after 10 minutes on hold -- no change.
I told the store that I was going to bring it back because I didn't pay $700 for a locked phone. Everyone has been nice but it's locked for policy issues and not for technical reasons. I flew to Canada when I bought my iPhone4.
And, AT&T is worse -- one guy told me 3 months and tech support said it had to be active for 6 months.
>> So, my AT&T sim card is not working in my SM-G900T model.
It is GSM/LTE unlocked (as are all Verizon LTE devices), but I'm pretty sure it doesn't have T-Mobile's LTE bands (or at the very least it doesn't have all of their bands).
From what I have been reading, on a Verizon phone, calls and data using GSM and WCDMA bands would work. But LTE bands are Verizon specific hence would not work.
Tl; Dr Voice /data using GSM/WCDMA. No LTE.

Does this mean, once unlocked, T-Mobile and AT&T versions would work on each other's networks including LTE?
I also noticed that with S5, there aren't GSM carrier specific versions. Meaning they are going IPhone route with making all GSM phones enabled that for that country's LTE bands. Is that right reading?

it is unlocked
I am using the verizon s5 on tmobile. It is unlocked and can be used on tmobile LTE. However there are only set modes. LTE/CDMA GSM/UMTS AND GLOBAL. Which means you can't use lte and gsm at the same time (no lte data and voice calls). I usually keep it on gsm, and when I need speedy data I switch it to lte.

How? If you put a TMobile SIM in the phone, or any other foreign SIM, it boots but receives no service. This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US.
Pictures please. For the record, my S5 doesn't register on a network with a TMobile or Australian SIM. The Australian SIM in a Nexus 5 roams to TMobile.

This was probably true about a year ago but the recent releases from Verizon, e.g. iPhone 5/5s and galaxy s4 has been fully unlocked world phones. I'm sure there are a few other phones... I think lg g2? I'm not exactly sure. But I have personally stuck my sim(T-Mobile) into my friend's Verizon phones (s4 and iPhone 5s) and they work right away after a reboot. Only problem might be an edit in APN for data and mms. Just sharing my experience, you should check out your phones again.

Not trying to be a jerk, but unless you tried this process in the actual phone in question, then you don't really know if it works. The phone DOES NOT just magically work on TMobile if you put a SIM in, you receive NO service. Now, I didn't go mess around with APNs -- typically those are only for MMS/Data. This is also true for several other phones:
Razr HD / Maxx HD
Galaxy S3
In the past, when the phones were SIM locked, a foreign SIM would prompt for an unlock code before the phone even booted into "normal" Android. That's not the case here -- because the phone is not SIM locked -- but I do believe it is network locked to VZW only when in the US.
For the record, I did try this in my S5. I will be going to Australia next week and will try a Telstra (or perhaps Optus) SIM over there to see what happens.

Yes, I haven't tried it on the s5, but I was pointing out fact that it does work on recent releases which someone confirmed worked on s5 by just plugging it in. I'm also correcting your statement " This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US." because Verizon apple does work in the US on T-Mobile and AT&T beginning from iPhone 5. I believe the 4s was still carrier locked.
I was a wireless agent not to long ago, so I know how these things work, not that it magically just works... I'm just sharing you how some recent releases from Verizon has been world unlocked and a few others have mentioned that they just plugged it in and it worked. So good luck and have fun in Australia.

OK Thanks.
It is odd that the apple phones -- and some of the Android phones -- are totally unlocked so that you can use them on ATT/TMobile in the US -- but some (like the S5, apparently) are not. I still am interested to know how some of the other users in this thread got their S5s working on TMobile...
Why would anyone want to buy a Verizon GS5 and use it on T-Mobile? The bootloader is locked and there is currently no unlock method available.
Would you like to exchange?
Would you like to exchange your verizon s5 with my tmobile s5?
i wanted to use it for verizon but the phone is locked to tmobile and at&t.
It would be ideol if i can find someone to exchange it with someone who has a verizon s5 and is looking for tmobile or at&t s5.
thanks,

I can confirm the Verizon GS5 is compatible with T-Mobiles LTE network I'm using one now with LTE all you have to do is go to settings mobile network and switch to Global mode some times you'll have to toggle LTE then back to global to get LTE to kick in.
I am able to successfully use my VZ Galaxy Note 3 and my wife uses her VZ Galaxy S5, both devices on T-mobile Edge, HSPA, HSPA+ (21mbps), and LTE (band 4) frequencies. These devices unfortunately will not do DC-HSPA+ (42mbps), but that's not a big deal for us because LTE coverage is good where we live. We have no issues with making voice calls, or sending SMS/MMS, and don't have to switch APN's or toggle between Global Mode or GSM/UMTS mode. We leave them on Global Mode with the correct APN settings.
Here's the guide I followed for both (with correct APN settings screenshots to accommodate for MMS on page 4 or 5 i believe):

How did you unlock the Verizon S5? BTW theres a bounty on doing so.

This is all new info to me. I have an AT&T galaxy S5 that I want to use on Verizon. Is it possible or do I need to trade for a Verizon-specific model?

[Q] Compatable with Bell Network?

I have been struggling for a couple years now with finding a phone that works both with Bell in Canada, and Verizon. Mostly because Verizon seems to be very picky with the phones it allows on the network.
I noticed spec wise the G900V in theory should work if I can get my hands on an unlocked one, but I was just wondering if anyone might test their IMEI on bells site (http://support.bell.ca/Mobility/Sma..._phone_or_smartphone_work_on_the_Bell_network) so I can see if they actually will accept it or not.
I'd hate to buy one only to discover otherwise (as happened with my current phone which spec wise should of worked, then verizon said no lol)

[Q] Will my Unlocked Sprint S4 work with a Verizon prepaid SIM?

I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?
Try it.
Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.

Verizon vs T-Mobile S5 for TING?

Hello all,
I will need some UberGeek advice for this one...lol
I use TING as my MVNO provider. They offer CDMA and GSM networks backboning on Sprint and T-Mobile. I had to get a new phone and ordered a Sprint CDMA version G900P but received a Verizon model G900V. It works perfectly fine on the TING network.
I am just wondering if there is any reason not to get this phone and to go with a T-Mobile model instead? I normally would go Sprint/CDMA but wanted to try out GSM this time. Both have excellent coverage in my area. I also know about the ATT/Verizon bootloader being locked. I have already rooted this and it's running Lollipop just fine a sper the instructions found in threads here.
TING told me the phone is no different essentially and there should be no problems. As always their cust, svc. was excellent and informative. This phone apparently has dual radios...CDMA and GSM. I don't have to worry about warranties, KNOW tripping or Verizon's bs. As I said, I am rooted and running fine. I will either debloat this sucker or go with another ROM. Right now THE only bugaboo I see is that there are so few ROMs for the Verizon model. I am not into switching ROMs. If I ditch a debloated stock setup, it would have to be very something very clean and stable based on Lollipop. Seems like CM 12.1 could be nice but right now slightly risky and they don't have the Fingerprint feature working either.
Does anyone feel it would be smarter to return this and get a T-Mobile model? Any food for thought or advice or "Here is why you'll regret the Verizon model 6 months from now" kind of advice?
Thanks in advance!!!!!!!!
Besides the locked bootloader, the G900V is the same phone as the rest of the S5's (of course with different radios for CDMA). If you're cool with just running stock firmware forever then keep the Verizon model. The T-Mobile model would allow you to do whatever you like with it though, as the bootloader is unlocked. Virtually no possibility of losing root.

Thanks for the response. Pretty much what I figured. I have it rooted and using Safe Strap and MIGHT toy with CM 12.1 since there are many out there with the Verizon model that seem to like it. Plenty of YouTube videos too.

Verizon version - GSM Unlocked?

Has anyone tried to use the Verizon variant on a GSM network yet? We've gotten lucky in the past with other Verizon prepaid LTE phones working.
I don't think the XT1609 is GSM capable. It has no 3G UMTS bands enabled, though it does have the full range of GSM 2G/EDGE bands enabled.
So, pretty much unless you're in a VoLTE area, you might be out of luck for voice calls if it is unlocked. I'm not even sure if this phone does VoLTE anyway though.

It would probably be a waste of time and $. Someone already bought one in the other Verizon moto g4 play thread and returned it because it looked like a no go. And without unlocking the bootloader, how would you flash a custom or alternate ROM to use the bands needed for GSM (as mentioned above). That's if it's a firmware thing and not a hardware limitation. If we want an unlocked Moto G4 play, the only option looks like we're shelling out $100 to Amazon for the one with ads or $150 without ads.

What link do you need, the link to the product page? Did you even research this phone one little bit before posting or was it a case of post now, think later? What network are you even looking to use this phone on? I'll tell you right now that several of the bands used for other networks are completely missing for this phone (can see this clear as day on any product or spec listing for this phone). Then there's the matter of this phone being carrier locked (it's not as simple as popping in a different sim anymore - Verizon changed their policy this year). People need to stop comparing this to the Moto e from last year because this clearly isn't. What else do you need to know?

EDIT: NEVER MIND. I just realized you were saying they'd need to flash a rom to enable the GSM 2G bands the phone hardware IS capable of. I thought you were trying to say you could magically enable 3g/UMTS bands that it's NOT capable of with a rom lol. Disregard the parts below about enabling bands the hardware isn't capable of, that's my misunderstanding!!
Original post:
I don't know what you're smoking bro. It most certainly IS a hardware limitation. You can't just enable bands that the antenna isn't capable of. SOME devices, very rarely, have antennae capable of more bands than are enabled in the radio firmware(NOT the Rom) but those are very few and far between.
Simply put, you can't make a 1609 into a 1607 just by flashing a new radio. If you could, then hell... I'd make every one of my old phones work with all carriers by turning on the bands they don't already have. Sadly, this is not possible.
As I said earlier in the thread, it's capable of EDGE (2g), and some of the GSM LTE bands that CDMA carriers use for data, BUT you wouldn't be able to call/text over LTE and it would fall back to EDGE for voice and sms (so no simultaneous voice and data) if you got a carrier unlock code from Verizon, but most GSM carriers are phasing out EDGE for postpaid accounts so if it's not a prepaid SIM it likely wouldn't register to the network at all for voice calling.
tl;dr unlocking the XT1609 for use on GSM carriers would be a very painful and unpleasant experience on prepaid where calls would go to voicemail when you're using data, and the SIM wouldn't register at all on a contract/postpaid account.
what about international use? is it possibly just locked in usa unlocked international for roaming?

I'm afraid that you're misunderstanding the meaning of "locked" in this scenario. It's probably carrier locked to Verizon prepaid no matter where you take it, but that can be remedied very easily (it was brought to my attention last night in a different forum that there are now unlock codes for these on eBay for around $2.50, so buying an unlock code takes care of that problem). But the real issue is the bands that this phone is capable of using and what is available where you're going and what network you'll be using. I believe the bands Verizon uses are more prevalent over seas, but I'm sure you can find this out with a quick web search.

I see. Need to find out what 3g bands get unlocked if any because according to gsmarena the 4g bands on this model are not applicable in my country and rolling 2g only is not worth it.

Simply put, you can't make a 1609 into a 1607 just by flashing a new radio. If you could, then hell... I'd make every one of my old phones work with all carriers by turning on the bands they don't already have. Sadly, this is not possible.
As I said earlier in the thread, it's capable of EDGE (2g), and some of the GSM LTE bands that CDMA carriers use for data, BUT you wouldn't be able to call/text over LTE and it would fall back to EDGE for voice and sms (so no simultaneous voice and data) if you got a carrier unlock code from Verizon, but most GSM carriers are phasing out EDGE for postpaid accounts so if it's not a prepaid SIM it likely wouldn't register to the network at all for voice calling.
tl;dr unlocking the XT1609 for use on GSM carriers would be a very painful and unpleasant experience on prepaid where calls would go to voicemail when you're using data, and the SIM wouldn't register at all on a contract/postpaid account.

Part of me says that the disabled bands is a firmware thing rather than a hardware thing since it's much cheaper for moto to make "one phone" with different programming, but it's probably just wishful thinking on my part. Either way, I'm sure Verizon locked these phones down so we'll because of the whole moto e thing last year (hordes of zombies flocked to bestbuy to buy $10 Verizon branded phones only to use them on other networks). All it took was a couple of commands in abd from what I remember (there was an ultra long thread about it at the time). Probably pissed off Verizon and I hope they lost their shirts. I'm sure that these types of phones are subsidized in some way since the unbranded ones are almost always double or more in price (especially with verizon- they usually have cheaper phones but more expensive service - great way to hook you).
And I know exactly what you're talking about with using this in stock form on gsm carriers. If you're in need of a laugh, go check out the thread for Verizon moto g4 play over on slickdeals. There was one poster who got this phone unlocked (via eBay) and was going to try to use this for VOIP with Google voice or something (data only I suppose) since he claimed to have excellent LTE in his region. I believe that he's in for an underwhelming experience and constant missed/dropped calls. I guess it might work if you stand in one spot all day. To each his own. Some people would do just about anything to save a few bucks. Here's a link and their username was TheLao :http://slickdeals.net/f/9195543-16g...ipping-free-store-pickup-best-buy-ebay?page=7
Just got off live chat with motorola with 2 different csrs neither knew anything outside of public info on what bands the xt1609 has or it truely has no 3g gsm bands.
may have to wait until someone who physically has this and can confirm what bands it has once unlocked? i tried searching for an app on store that can tell you available bands on the device but gave up after about 4-5 apps.

I'm sure in some phones it is probably just a firmware thing. I remember some of the early Kindle fire models that were on the low end were really underclocked high end models with a smaller NAND. If you rooted them and flashed a new kernel, you could enable Bluetooth and set the clock speed up to match the higher end model and all you'd be missing is some storage. In the case of the Moto g4 play, though, it's probably cheaper to just leave out the physical antenna hardware for non VZW bands than disabling them via firmware. That's likely just a matter of dropping a step from the assembly process, so it wouldn't cost them any extra... Might even save a few pennies per run. But I'd imagine on high end flagship devices where it's a different model for every carrier, it's just a firmware thing. That's probably the REAL reason some phones have locked bootloaders. Like the LG G4, the only one with bootloader unlock is the international version with all bands enabled. I bet if I COULD unlock the bootloader on my sprint LG G4, I could turn it into a GSM phone.
And LOLOLOL about that link. Dude is going to hate life. When my LG G4 was in for repair and the Moto G4 Play hadn't shipped yet, I was using a LG G Pad F7 LTE tablet with Google voice, using hangouts and hangouts dialer for sms and voice. Missed calls SO many times because it would take too long to start ringing on my end, and I'm in one of the major US markets so LTE coverage is literally everywhere.
Welp, TIFU. I bought two of the Moto g4 play at walmart... got home and found out that Verizon locks 4g phones again. Paid for an unlock, found the phone doesn't allow connecting to GSM networks, but that is because even with a GSM sim in the phone it still only connects to Verizon. With my t-mobile sim in the phone, I make a call and get the "your call is being transfered to a representative who will take your credit card info to complete this call". Leave it to verizon to only allow the phone to connect to their network even after you unlock it...
Xt1609 doesn't have connection of gsm or 2g
Hi! I bought a "Moto 4G play" of Veirzon USA (XT1609). Unfortunately, My network operator in Mexico (Telcel) hasn't compatible with the VoLTE.
The cellphone doesn't have connection of GSM or 2G only LTE 4G. I did unlocked it and use everything, photo, video, WhatsApp. The cellphone recognize my SIM Card and network carrier, but I can't make, or receive, calls.

Well, that's what the Moto E 2nd gen did out of the box as well, they removed the setting to swap CDMA/GSM in the menu, but the folks over in that part of the forum figured out that using the app "Network" from the play store, and a sequence of turning on/off airplane mode, they were able to switch it from CDMA to GSM and make it stick. Otherwise, it would keep trying to connect to Verizon just like you describe.
So it doesn't mean anything that you didn't get it to work immediately after unlocking. You probably have to force it off CDMA in a similar fashion. Bigger issue is whether or not the phone will be able to actually access the appropriate bands you'd need, whether because the hardware doesn't support it or because it is disabled in firmware. We don't really know for sure yet. But if you've come this far and have a penchant for torture but don't want to give up until you know for certain, give it a try!
