I recently switched from straight talk to verizon's own pre paid plan after being fed up with straight talk. When I first got the service active everything was fine. I flashed the CM11 AOSP rom snapshot. I then proceeded to try and update my roaming capabilities by dialing *228 which the automated system told me was successful and ever since then my phone will not stay on LTE. It will only goto 3G. If i try to force the lte only mode then my data will work but i wont be able to make calls. I have tried going into stock recovery and resetting factory to try and clear the NV and flashing both the kitkat and lollipop RUU to no avail. Any help would be greatly appreciated.
You might have damaged your Sim card by dialing *228, well I don't know about damaged, but I know Verizon phones locked to their network that uses 4G LTE Sim cards are blocked from dialing *228 because of the reasons you described.

So maybe i need to go get a new sim card then. Thats what i figured hopefully i can get to the verizon store before work and grab one.
Hey,
Were you able to get it working again?
I have the same issue. I dialed *228 like an idiot and my phone activated on 3G and won't get anything else.
I've had Verizon reset the connection on their side and I went to the store and picked up a new SIM but I still can't get LTE. It's driving me crazy. I've tried restoring to a prior backup, factory resetting the phone. Nothing gets me LTE.

Hello, I bought a SIM card from straight talk hoping to use it on my merge because I have seen people online that says I can do that as long as i have my SIM card unlocked. But after I got the card activated and put it in my phone it don't work. I try changing to GSM and using their APN but I have no signal, the mobile network just stays unchecked and I cannot check it. After a few minutes my phone suggests switching over to global mode and i do have mobile signal then but still no connection with anything. I called the straight talk woman and she told me it only works with AT&T or T-Mobile phones but it just don't make any sense to me that you have to have one of those previous carious just to get them as a new carrier? Am I missing something here?

Thanks to the helpful people over at 2fastroms and their quick response I found out that you have to have the 1.06.00.0910 verizon radio flashed to your system. You have to install the radio in the boot-loader and not the recovery menu, it took me a minute to figure that one out. Just informing anyone that has the same problem as me because I could not find it anywhere else on the web. Anyway credit to jianC for the help.
My husband finally let me root and rom his S3 (I have a Gnex). Unlocking the bootloader and rooting (using Odin) went well. When I installed SlimBean+GApps, however, we started having an issue. He kept losing 3 & 4G signal. We didn't know about the roaming issue, so I had not backed up the IMEI. I flashed Clean Rom, and the issue is partially fixed.
The phone's signal is fine now, 3-4 bars 4G most of the time. The trouble is, we can't dial out to any numbers, and any calls to the phone go straight to voicemail. We've pulled the sim card and let it sit for a bit, but that didn't help. Dialing *228 (as Verizon tech support had him do about 4,583 times) just brings up a message about the phone being activated by the sim card, and roaming capabilities being updated. All tech support had to say was that Google Voice was probably the problem, even though we've both had it for ages with zero issues. :/
Any ideas? I don't really want to unroot and take it in to the Verizon store, but I will if there is no alternative.
EDIT: Just discovered that 4G is only working when "Preferred network mode" is set to Global, rather than LTE/CDMA.
*228 is for 3g phones only, it does absolutely nothing for LTE sim phones. Here's your solution btw.
I knew it! I kept telling them I didn't think that was supposed to do anything when I have a sim card. Crazy first string tech support. They also didn't know my battery was removable.
Will try the things listed in that link, thanks.

Haha Verizon lost credibility with me when I rented their global phone for travel last summer and when I got back to the US the instructions to get my GSIII working began with dialing *228. There wasn't even a warning about it being unnecessary for LTE sim phones.
Good luck and let me know how that goes.
I picked up a mint verizon s3 local on a trade for some scrap phones I had. So here is my issue. I put in a sim(at&t) and got the switch to global notification but it never gets signal. Phone info shows -120dbm 99asu. Figured since it was free I would play with it and installed hyperdriver rls 16 still nothing. Took everything back to the first stock ics nothing. Currently have it on jb 4.1.1 nothing. I started to wonder if the radio was trashed so I dialed 911 with no sim in the phone and it popped up 3 bars and made the call.
Am I wrong in thinking this phone will work on US networks with a sim? Anyone ran into this problem possibly can maybe point me into a direction to get it working. The phone is clean and not blacklisted and it reads the different sims I have put in it I just can't get any signal to pull up other than an emergency call. I know there is signal my s4 is on the gsm network sitting right next to it.
Thanks in advance, I have been searching since yesterday for a solution.
****update.....Went ahead and took it to 4.1.2 stock and happened to find an old verizon sim. Phone picks up verizons network without issue. Still nothing when using the at&t sim.
It isn't working for AT&T because you haven't set up the appropriate APNs for that network. Google AT&T APNs. Reboot after making the changes. CHECK FOR TYPOS!

I thought I would at minimum show signal even without adding the apn. From everything I have read its talk ready just inserting the sim. Will look at adding apn's this morning.
Final update. Still no joy on getting it to work and I listed it for sale.
There's a thread about getting vzw s3 to work on T-Mobile, I'd imagine you'd need to follow a similar process. And FYI, all phones will call 911, sim, no sim service, no service, they'll call 911. My niece was playing with one of my sisters old, no longer connected phones. All of the sudden police and ambulances showed up. She had dialed 911, they tried to return the call unsuccessfully so they used the phones GPS info and showed up at the house.

As the title states. I was on the ML1 radio. Put a T-Mobile SIM card in and I had data/voice/texts. Everything was going well. I decided to put my Verizon SIM back in and I lost connection to the mobile network. LTE and data worked fine for me. Just no texts or calls were going through.
I tried switching to ATT in the networks section and switching back to Verizon, but still a no go. I also took my SIM out and then booted up the phone without a SIM. Turned it off and put the SIM in (Verizon), still a no go on the mobile networks.
I ended up restoring a backup I had made a week prior and every thing is back in order. I still had an IMEI during all of this.
Any suggestions? I am afraid of going abroad and using a GSM SIM from another carrier, then coming back and having this happen again. Also my "global" network mode option was not there after I had inserted my T-Mobile SIM and when I was trying to get back onto Verizon.
Any input would be greatly appreciated and thanked!
Hey Folks,
I have a Nexus 5, which I bought from the Play store and have been using on Sprint for the past year. I'm switching carriers to AT&T and would like to know if my device will work on their network. I went to an AT&T store and tried swapping out my SIM for one of theres but the "AT&T" logo didn't show up on my phone and I wasn't able to use voice/text/data. Then, when I tried swapping my sprint SIM back in I had a ton of trouble, in the end, the sprint store had to factory reset my phone to get it to work again. I guess my question is, are there any specific settings that need to be changed or a specific manner in which i switch the SIM cards to get it to work on AT&T? A Sprint rep told me it work on AT&T but that can't be right, the phone is unlocked after all. Any and all input is welcomed!
A lot of people here use ATT me included. You'll have to change your APN to ATT. You also will have to give them your phones IMEI. After that you'll be all set.

I used to switch sims between ting(sprint MVNO) and ATT since I work in areas sometimes that does not have att service, and I never had a problem going between the two. Did you try to reset the radio on the phone?

Hey guys,
I looked for APN settings on my phone and googled it but I couldn't find those options. I tried updating the profile before, updating the PRL, restarting it multiple times and turning the radio on and off. Also tried switching the network type between Global and LTE options multiple times, which only worked < 1% of the time. Finally, I went to the sprint store where they did a factory reset and now it only works on 3G (no LTE). This is a family plan where we're switching to ATT permanently. My sister is sending me some sort of "customized" SIM card for my phone (they took all of my phones info) that should work on ATT. When I go into ATT again to test out my phone, are there any specific settings I need to change or a certain manner in which I switch the SIM cards to test my phone if it works? I wanna test it with a random ATT sim first and not my "customized" SIM card because our ATT line isn't activated as yet, only sprint is.
