Ok so I just have a quick qustion and I have searched but can't find an answer. I think my 4g radio may be broken because when I try and turn it on it sits for a minute then says unknown and turns back off. The coverage map shows me having 4g in my area but it could be wrong. It seems to me that I should be able to turn on the 4g radio and it will be on and regardless of signal and will keep searching for a signal but I've never actually had a working 4g connection so I don't know if this is regular behavior or if my 4g is defective and I need to get a replacement.

try reflashing to a stock rom,either dg27 or di18...i had this issue with my first epic,then di18 was updated on my phone and my 4g didnt work,quite a few of us had this problem.i just returned mine in and showed sprint that it was a hardware/software defect on their side.hope this helps

Just wanted to update incase anyone else has this problem. I tried flashing back to complete stock di18 but still no 4g so I took it in to sprint where they just did a data reset and then sat there scratching there heads when it still didn't work, they were absolutely no help and at the end they pretty much told me I could buy a new phone or live with it. So took it back to radio shack where I bought the phone and the replaced it no problem. Now my 4g radio works great and I even have coverage in my erea B-)
Thank you for your advise

My DX seems to be dropping signal from 3G to 1X constantly. I'll go from full bars on 3g to 1 bar on 1X? I did the *228 option 2, I update my PRL often.
I'm still on stock 2.2.1 w/ root. Does anyone know what could be causing this. I've had this problem since I bought it in November.
Thanks.
I've had similar issues for a couple months now. Verizon tells me they are upgrading the Alltel towers here (east central Ohio). Every time I ask them about it they tell me it should be ironed out by the end of the week or some time the following week.

Also have this problem from time to time, but I'm on Fission 2.4.3. No idea what's causing it, but I may SBF and take it back to Verizon.
Yeah mine does this as well. Only fix I know of is to turn airplane on and wait a sec and turn it off and poof, 3G again.
I don't think it has anything to do with upgrading their towers though, it's likely to get you out of the store and to save them time from giving you a replacement. I can only think it's something with the antenna in the phone.
the update was supposed to also update the radio portion of the phone. Did you get the update?
The baseband I have BP_C_01.09.07P This may vary by geographic area.
I had this issue when on the stock ROM, but it has not happened in the weeks since going to the 320 leak and now to the 340 OTA.

anyone with the 4g LTE experiencing this error?
yesterday (December 6) my Xoom mysteriously gave this error while doing absolutely nothing on my desk. I rebooted it twice and wipe clean LTE sim card and reinserted it. at first i couldn't get any connectivity to verizon services the whole day. but this morning i saw the 3g service come back online, but still i'm getting the 4G LTE sim card error.
i tried to google search this problem and only found one post that coincided with my time frame. is there something wrong with my xoom or is this verizon fault?
Noticed the same popup this morning, rebooted and it went away and came back...
Haven't messed with it yet. Good to know I'm not alone.
Also having the same issues with my Xoom. Didn't have any connection at all yesterday but this morning 3G is working. We'll see if they can fix this.
Its an issue with the 4g outage some sim card's data was erased just get a new 4g one and it fixes it did it yesterday and now it works fine
it should be free as well from Verizon mine was at least

Just got off of the phone with Verizon and they said that there is a 4G outage and that they're working on it.
That happened to me this morning but was fine after a reboot. The possibility of this thing screwing up even more makes me want to demand that Verizon let me out of this contract as I've had nothing but crap from them and Motorola for 7 of the last 9 months.

I am at work now which only has 3G coverage and it seems to be working OK. Just have the annoying message. When I get home (which has 4G coverage) we'll see whether 3G still works.
Ha!! This just happened to me a few minutes ago. I got the Sim Card Authorization Error & my phone has been freaking out for the last hour or so. Having flashed a new 4G ROM this was waaay to coincidental for me. Glad (bad word choice) to see other people are having the same issue too.
It's Verizon's network.
http://www.gottabemobile.com/2011/12/07/verizon-suffering-4g-lte-outage/
Having the problem too and I'm completely stock.
Same problem here and also stock.
Back home (N central NJ) in the 4G coverage area, my Xoom is bouncing between "No Internet Connection" and "Verizon Wireless 3G". It doesn't stay connected to 3G long enough to be useable. Stock 3G Xoom, upgraded by Motorola to 4G and running the recent 3.2.4 update.
Earlier at work (NW NJ) in the 3G coverage area, things were stable.
Not seeing the SIM card message any more though.
Same here. Just got the sim card authorization error. Glad I'm not the only one.

It's a network issue with Verizon. My XOOM is giving me the same error. When I called tech support today they couldn't tell me when it would be resolved, but apparently it's affecting almost all 4G phones and tablets in the northeast area. Hopefully it will be resolved tomorrow.
My 4g is working normally now without any reboot of any sort. Guess Verizon fixed it

New phone, everything was good now no cell signal at all. I was rooted w/ CM and cell signal went completely away almost like the SIM card is bad. SIM is 2 days old and was cut at the TMO store. I went back to stock JB Occam firmware and that did not help. The kicker, Sim works in my GNex w/ adapter so could be contacts in the G$? Anyone else have similar issue.
On my HTC rezound I get low signal and my 3g cuts out a lot toggling airplane mode does nothing and I'm using cm9 also cm9 messed up my Bluetooth. I'm trying to fix these issues but I've had no luck.

I was hoping the tower nearby went down and that it would function when I got to work. Still doesn't work on the N4, works on the Gnex. Looks like it's going back to the Google Ship.
Unlocked and rooted.
Was on latest CM 10.2 nightly.
4g started coming in and out and eventually I just lost 4g. Everything else was fine.
Friday I went to the store and got a new sim card. Since I was still on CM10.2, I couldn't *228 and reactivate because the keyboard doesn't come up once you connect, but eventually, after a few reboots my 4g was back.
As an aside, they noticed I was unlocked and rooted but since it was a reseller, not a corp store, I think they let it slide.
4g works fine the rest of the day Friday.
Saturday, does the same thing. In and out and then finally lost.
Powered off and replaced the sim a few times. No luck.
Wiped and flashed my last verion of Stock and still no luck.
Went into ##7764726 and found where I could force LTE only (You can't do it through stock settings)
Reboot and 4g works fine, but I lost regular mobile service. ie; can't make phone calls.
Went into settings, toggled between Global --- LTE/CDMA got my mobile service back, but lost 4g again.
Did this a few times. Consistently the same results.
I haven't used Matt's utility yet to go back to bone stock, but before I do that, any other ideas?
TIA

Did you ever mess with the "band" in the 3 dot menu in the phone info hidden app? Or test mode may also bork your radio partition in the same unfixable way. Rsd is the only. DIY or see my restore sticky. Data wipe is a must before you rsd.
I didn't see a 3 dot menu and so I didn't mess with the band. At least not that way. I'm not using a third party app. I just dialed the key sequence to get to the settings.
I'll try RSD tonight when I get off shift or as soon as I can this week.
BTW, I hadn't made any changes when this first started other than restoring VZW settings in build prop for @ecips CM 11 rom. But the build prop has since been written over several times each time I wipe and flash or restore a ROM.
Thanks.

After making my last post I went back to @ecips OP and saw two lines in the build.prop that aren't in my current build.prop. I wonder if that's the difference.
These are the two lines I don't have:

I cannot say. Restore your stock rom though recovery & test.
Looked around a little more and Band says: US Cellular 800mz.
I'm on VZW. That could be it.
I don't know how to change it on my phone.
I can't RSD till I get home tonight.

Cellzealot knows bout this.
Correct me if I'm wrong, but if you #228 it kills your LTE. At least it does on Verizon...
IIRC when you do that, you need a new SIM...
Anyways...
I think you might have a weak 4g signal. When it's on 4g/3g/1x, it defaults to 3g due to the weak LTE signal. When on LTE only, it has to stick on LTE. Of course since LTE can't do voice or SMS(?), those won't work...

I've read that before.
This happened though before I tried *228 for the first time.
I've also been in and out of strong 4g areas, so I'm not sure it's a signal strength issue.
Also, when I look at my signal strength, I'm receiving 1x and 4g signals with the 4g signal generally being stronger (lower db).
Interestingly, SMS works when I'm on LTE only. The only problem is that I can't make or receive calls.
Going to try a few resets now with RSD and/or Matt's utility.
Last options will be a new sim, or gasp, trying to get the phone replaced. I've had it less than two months, so time-wise, I'm good for the warranty. Unfortunately, it's unlocked....
I couldln't get RSDlite to install on my PC. Win 7 64bit. I got an administrative rights error. I'm the administrator on my PC. I know there's a fix for it and I did a few searches, but my brain is shot.
I used Matt's Utility and restored this back to the stone age and didn't do any of the google updates. Still stuck on 3g.
I'll try again tomorrow, but chances are my sim card is shot. But, why would I go through 2 sim cards in one week?
I also looked at @Zealots thread. That seems to be more for flashing a VZW phone onto another network. I'm in the opposite boat. But again, the brain's tired. I'll try again tomorrow.
Thanks guys for your advice.

I tried that. Right click on the .msi, but Run as Administrator wasn't an option. I've run into that before with other apps and that's worked.
I downloaded RSDLite 6.1.5 (I think), unzipped it and then installed. I'm thinking I made my mistake somewhere in there, but I'm not sure where.
Also, as a side note, I did some reading and know I understand why @Zealots fix may help.
Voice is basically over CDMA which is ruim. LTE is basically gsm which is sim. I may need to tell my phone to actually use sim when it's set to ruim/ in settings. The full restore through RSD might achieve the same goal.
At least I think that's right.
I also understand that we don't have true voice over LTE. VZW LTE devices effectively are using two radios at once. the 1x/CDMA/EVDO radio and the LTE radio.
Both seem to work on my phone, just not together.

Ah right. .msi files theoretically should attempt to elevate while running.
That's not quite the case. LTE has no voice built in at all. Technically, when your phone switches from 3g to LTE, it's jumping network types. VZW doesn't have any GSM voice capability - it's all done over CDMA. When your phone is in LTE only mode, you'll never have voice. At least not unless we get LTE-A on the M, assuming that's even possible. Interestingly enough, the SIM handles CDMA affiliation as well (same as doing #228 does) - all your account data and PRLs and stuff are on the SIM card.
Yes there are two radios (also why LTE is such a battery drain - it's literally a separate radio board).
A full restore would be a good idea, and you could also try someone else's VZW SIM in the phone. You may have 3 different points of failure here: hardware (phone radio is screwed, you're SOL), software (full restore or OTA update should fix that), or SIM (get a new SIM... Again... Lol). If we can isolate it to the phone or SIM, that should help us figure out the problem.
EDIT: WAAAIT a second. You're on 10.2? Was your network mode on the default that came with the ROM? Cause that doesn't work. That might be your problem
EDIT 2: you need to be on "LTE / CDMA / EvDo". Anything else probably WON'T work.

I used Matt's utility/suite and restored to stock. I believe that uses RSDlite. Once I restored to stock I had the same problem. I don't know if using just RSDlite does the same thing, but once I get it installed I'll give it a shot.
Regardless of which ROM I use I'm on LTE/CDMA/EvDO and I don't get LTE.
I can get a good LTE signal if I choose LTE only either through the ROM settings (CM, AOKP, etc) or ##program on stock.
I've had the phone almost two months and been on a variety of ROMs; stock through 4.4 based. This only started last week.

So, let's say it's the card and I swing by and they pop in a new one. Any idea how to keep this from happening again? Or can a bad radio(s) fry a card?

Bad radio boards could fry a card. I'm sure it's possible. Whether it's happened before or not, I have no idea.
Yeah, I'd try a new SIM. Looks like you might have gotten two lemon SIMs in a row...

It's a retail store that sells exclusively VZW but it's not a corporate store. Maybe they get the leftovers.
