I have done the USA unlock. It was working fine. Then I factory reset it. Now, the roaming indicator is off. And I'm unable to switch it back to gsm to use my carrier TMobile. I tried putting a sprint Sim and it doesn't go away.
The mobile network is greyed out. In the notification menu on the bottom it says roaming indicator off where it used to say T-Mobile.
Please help
I think I fixed it. Downloaded radio switcher and manually changed it. I'm going to restore phone and double check to see if it holds true

hi. i just got this phone in the states before coming down to panama. it is verizon, but i called them and they gave me the code and now the phone is unlocked....but i can't get coverage here in panama. i've tried sim cards from a few of the local operators and none of them seem to work. i sure hope someone can help....here's what i've done so far: (oh, pls b patient, i'm a bit of a technophobe)
-unlocked sim. phone gives me sim lock is disabled message....that means i'm good to go, right/
-set phone to gsm only mode.
-software is androaid version 2.3.4
verizon global services told me that everything was as it should be and that the phone should work w/ a local sim card so i'm not really sure where to turn to......hopefully someone here can help. verizon also told me that the phone should work on the frequencies here. i have a claro sim card, but have also tried movistar, digicel, and masmovil. i was told that they use either 850 or 1900.
so, i'm totally stumped. hopefully i'm missing something stupid....btw, tried the sim in other phones (from europe and panama) and it worked w/ them. don't think it's a hadrware problem, but am i missing something? is there a setting change? do i need some kind of software update?
thanks!
update- get cell phone reception w/ gps on
don't know if this will help anyone get to the bottom of this issue, but i realized that when i have the gps on, i get full bar coverage. unfortunately, i can't leave the app on in the background. this makes me think it could be a hardware issue....bad antenna? anyone have any ideas
Same problem
I have the same issue as OP. Got my phone sim unlocked, and it runs on SenseMOD-2012-05-18-225643 Android 4.0.4.
For once I did a factory reset, skipped verizon activation (can´t do and won´t work because I´m not in the USA and do not have a verizon SIM or service), set my network preference to GSM/WCDMA, and the network wasn´t working.
Rebooted, my network is identified as soon as it starts, but then it goes to "No Service". Try to search for network but my carrier does not appear.
Any help?
EDIT:
Playing around with the phone, setting GSM as your network and restarting the phone let me make phone calls. No internet though and the APN was configured correctly. The "E" symbol for the internet blinked once in a while, but never got service.
Also, playing around some more, got my phone to not recognize the network again by removing the SIM another time. This sucks.
Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).
*bump*
Any ideas?
Did you put a check mark in data roaming?

I've tried with and without it, it doesn't make a difference anyway.
Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)
Update to full NK2 firmware and see if that will fix it

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?
I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
***SOLVED*** Thanks!
Hey guys I'm in need of the default settings for a Sprint S6's Testmode Menu. Specifically, the Network Controls, GCF, Preference Mode or pretty any way to set the S6 back to the way it came with Sprint plus the GSM unlock for T-Mobile. In settings/Mobile Networks/Network Mode was Auto before my mishap with the settings. I also had two APNS for TMO one for LTE data and the other for MMS and in service mode, it was set to Global. I changed stuff around in Testmode Menu and thought I had put it all back to how it was, but now when I set it to GSM/WCDMA/LTE, I will get GSM in areas I know for sure had full LTE. It will also say GSM/WCDMA/LTE in Network Mode through settings, which isn't an available option through there and which was originally Automatic when working. I wish to get back to the way things were. My phone was unlocked via GC Pro from an XDA member. I had changed the settings in hopes to improve my signal at homr because going to my neighbor's house improved signal. M changes worked, but randomly would say No Service. Anyway, please please help! If you have any other suggestions, that'll work to.
I have a pixel 3xl, up to date stock non rooted, on straight talk lte/cdma Verizon network. I got a text saying straight talk now has VoLTE so I tried to find it in settings but there's no option for it. When I search it it comes up but when I click it it goes to mobile settings and it's not there I did the *#*#4636#*#* and it's also grayed out there. I changed the network mode in that diag screen to lte/cdma to see if that helped, was on global before i think. Still no VoLTE and for some reason I can't make calls. I have data, can send and receive texts but when I go to call it says no network. Removed Sim card didn't fix it, restarted it. Safe mode doesn't help either. Tired clicking trigger carrier provisioning, updated the smsc. Change mobile network to lte only, back to global, lte/cdma. I have no idea what else to try. Straight talk is basically useless for customer service so I haven't even tried yet lol.
Update!! It works!! Somehow I either damaged my sim card when I switch from my pixel 2xl to this 3xl and it somehow lasted till now. Or when I changed my network settings something wrote to the sim?( And it messed it up?? IDK much about how the phone and sim interact with each other)... But I did have a 2 year old sim card, it did not have VoLTE or wifi calling capabilities I now realize. So I bought a new SIM card at Walmart and activated it though the straight talk app on my account and kept the same number. Works perfectly and I now have VoLTE, no wifi calling yet but the option is now there and lets me click it but it fails. Doesn't matter to me, I'm just happy to have VoLTE. I'm leaving this post because straight has horrible customer service and I could find anyone who ran into this specific issue.
Got the LG G8 unlocked Amazon Alexa edition last August (2019). I use it with Sprint. I love the phone and it worked great, until a month ago.
All of a sudden, I can't make or receive phone calls or text messages, but I DO still connect to the Sprint cell service (I have bars) and I DO have working 4G LTE Data. Literally, one day it worked and the next day it didn't. I hadn't powered cycled the phone or anything between it worked and when it suddenly didn't. It just stopped working.
When I try to call out, the dialer gives me an "Out of service area" message, even though I'm within my service area. When someone tries to call me, it goes straight to voice mail as if my phone is turned off, except that my phone is turned on. When I try to send a text, it sits at "sending" indefinitely and never sends. When someone sends me a text, I simply never receive it.
Sprint, I do firmly believe, has done everything they can to troubleshoot it and proven it's not a network issue. Several different kinds of resets, including a factory reset. I was able to reactivate an older LG V20 on my account and it works just fine.
The phone is still under warranty with LG, and I was able to send it in for repair at no cost, but they did not find anything wrong with the hardware. They did do a software update of some sort, but that did not resolve the issue.
So now I'm essentially stuck between both Sprint and LG saying it's the other's issue. First unlocked phone I've ever bought and it bites me in the butt.
Any other ideas for troubleshooting either on the phone itself (beyond all the standard stuff which I've already done; I mean, if a Factory Reset doesn't help...), or with Sprint?
Thank you!
I had the same problem with Amazon variant. I used an app called Hidden Settings Muiu and went to "Phone Info" then switch the Preferred Network Type to LTE only leave it on there until it says LTE on data and no network on Voice then switch to LTE/CDMA and it get 1xRTT. Ive tried tweaking settings and everythingelse but no luck that seems to be 100% effective but anytime you **** with your network or restart you'll have to do that.
Edit: Do Global(PRL) then LTE only then to LTE/CDMA. Otherwise itll stay on EvDo for data not LTE.

Did try that and gives me data but no cell service. Thank you though
Had same problem from a newbie...
I used ##873283# with dial key pad. It took a few times but finally worked. As soon as you power off or restart your phone, your back to where you started.
I bought mine from bestbuy 1 1/2 yrs ago. They are having lg send me a new one...
Lg v8 thinq This is the model I had* LM-G820QM.
Good luck.
Had my settings on LTE/cdma with roaming turned off.
