Hi,
I recently went to India and thought it would be cheaper there to get my note 2 unlocked but, the person who tried unlocking my device got mad at me as my phone was rooted. He said, everyone wants to be a developer nowadays and thus it made his job harder. He asked me the model number of my phone as it shows GT-N7105 because I have DN3 v 5.2 installed but it is actually sgh-i317m from Telus in Canada. He gave up and said he was unable to do it. After coming back home, my original sim that I have been using in the same phone, does not work anymore. There is no network. My wife's sim card, which is from another provider, works now though it never did before. I though there could be something wrong with my sim card so I tried it in an old phone and it works perfectly in it. What would you suggest, I should do to try and resolve this problem? I am thinking of erasing everything from my phone and factory resetting it. Eagerly waiting for your expert suggestions!
Just to add: I chose factory reset option from under the settings menu and wiped all my data but it still does not work with my sim. I also, went under the available networks settings, chose the option to search networks and then selected mine (telus) but it say's no service (telus) not available. There is another message in the notification bar, which reads "data roaming: You have lost data connectivity because you left your home network with data roaming turned off". I am not sure if that tells you something related to my problem but I though I should mention that as well.
IPosting this more as a FYI from my recent experience with my Verizon LG G4 phone using over seas (Vietnam vs. originally in the U.S.). The phone is currently rooted with firmware VS98610BB (10B) with Android 5.1. The phone is no longer on Verizon Wireless (paid off device and service cancelled). Earlier in the day, my LG G4 experienced an abrupt "SIM Disabled" followed by "No SIM - No Service". I was in the middle of surfing the internet via Viettel's 3G (Vietnam cell phone carrier) when I lost the ability to use the cell phone service. At first, I thought my phone was suffering stability from the drops and banging that happened to the phone recently, however I believe the accidents were negligible due to a soft transparent TPU cover I have on the phone. I then thought that my SIM was probably banned, blacklisted, or blocked from the carrier. I tried restarting the phone. Doesn't work. I removed the battery and reinserted the battery and powered on the phone. Still doesn't work. Finally went to a local Viettel retail store and the representative checked the SIM. It was working in her phone (phone call made to the retail store and phone call made to the phone having my SIM).
I made further searches online to see what other things to try or the possible issues. Saw some may have hardware defects, but in order to eliminate the SIM reader was broken, I decided to whip out the Verizon's SIM to try. The Verizon SIM verified that my phone didn't malfunction. So I was going to try the next solution is to mask the IMEI to verify my SIM was blocked on Viettel's network. I took out the Verizon SIM and stuck in Viettel SIM. To my amazement, Viettel network was picked up again.
I did notice that while I was at the Viettel store, my APN entries were wiped out or erased somehow. I reentered all the APN information but it didn't help while at the the retail store.
Well, the conclusion is: swap SIM into the G4 to see if it resets the network and SIM information, then stick in the SIM you're using.
I hope this is helpful to those who experienced the same issue.
Ran into a similar problem as indicated in the above post (no carrier signal found) with another LG G4 under my care and this time, trying the above workaround did not work for the second LG G4 phone. It appears that something must have corrupted the system files or other files. What I additionally did was cleared out all of the credentials (Settings/Security/Certificate management/Clear credentials). Also, I wiped out the cache by performing Power+Volume down keys on boot up to access boot options of wiping cache (rooted phone). After rebooting the phone one more time, everything went back to normal. What bugged me was that the phone was charged up to 80%. After another reboot, it is now at 100%. Strange. Another thing that was strange was when enabling airplane mode, to disable it from the settings menu was grayed out, i.e., cannot switch off and on. However, the quick settings still worked. But everything is in working order now. This leads me to believe file corruption has happened to both LG G4 phones. Even the APN list was wiped out.

what rom are you using? stock or custom?
I got a Verizon Galaxy Note 8 because we are switching to VZW, but not until Saturday. So now I've got this amazing new phone, and I can't do anything with it because I'm stuck without being able to activate until I have a SIM card for it. Any way to bypass this? And if I do, can I activate it later without having to hard reset?
EDIT:
Answered my own question. I noticed it was showing 4g coverage, so I popped the SIM try and turns out they helpfully shipped it with a card in there, so I removed it, and was able to activate with Wifi.
I had a vzw galaxy s 5 (bl unlocked and rooted) and when I upgraded to the vzw note 8 it came with a new sim card already installed (I assume, as I have never actually checked). all I had to do was call the 1 800 activate my new note 8 phone everything activated and off I went.
To bypass activation on the Verizon Note 8 Disconnect from WiFi "not needed" Remove any sim card from the phone "not needed" Then go through Setup Wizard. Then selecting Skip on every screen that you can except for EULA screens you need to accept the terms but not all options need to be checked this is up to you. Even when connect to WiFi screen comes up just select skip and you will be just fine and complete the setup giving you complete access to phone features Good Luck!
I've tried everything, so hopefully someone can shine some light into this issue.
I bought a new (unused but from a 3rd party) Samsung Galaxy A50 (A505U) Verizon branded and unlocked. Got a sim card from Visible and went to get it connected. Nothing. WiFi works, everything works, but no cell service.
Here's what I've done (some multiple times)
- reset everything to include network settings, hard reset, etc
- removing the sim, resetting, putting the sim back in. I always get a notification saying the sim card is removed and it goes away when I put the sim back in, so it is recognizing a sim card is in there
- switched sims with another Visible phone/sim and nothing. Both sims worked on other phone but neither worked on this phone
- tried getting into the hidden menus but none of them worked
- talked to Visible tech support which upgraded the issue to the highest level and concluded it's the phone
- Visible believes it's the APN settings but I cannot edit current APNs nor add new ones (grayed out)
- manually add networks, I can see Visible, TMobile, ATT, and some weird numbers, but when I try to connect to Visible it says cannot register on the network, other networks say the sim is not setup for them
- sometimes I get the icon that shows all bars but they're grayed out, sometimes it shows 3-4 bars lit up, sometimes even shows a 4G icon, but mostly the grayed out bars
- sent the phone to Samsung, they tested it and found no faults, guess the hardware is good, ruled that out.
- got into dev options but I'm aware the OEM unlock is not on option on the A505U, not sure if I can change anything else.
I'm out of options. Any other ideas? I think if I can either get into the hidden menus I'll be able to diagnose it better, or if I can somehow change the APN settings I'll be able to set it up. Visible tech support thinks it's the APN, which makes sense to me, but I can't change them.
Any help is greatly appreciated.
I was able to get into the CSC change function, there's not many there, but would changing the CSC help? If so, which should I go to?
I've had a similar issue. Was working fine until the Android 10 update arrived. Since then, it won't work with my total wireless sim card. Tried 3 different sim cards on it, but nothing. Can't add it do anything with the APN, and getting into the phone info hidden menu doesn't help any. I suspect it's a bug in the new firmware or something like that. Works fine with a Verizon SIM though.
Update: Verizon SIM no longer connects to phone. Still works with LTE data. It seems that the CDMA radio quit working with the update to Android 10. Must have been collecting to the Verizon network with VoLTE until it updated the provisioning or something.
So, I finally figured out a workaround for mine that was able to get both data and voice networks to connect while using total wireless, which is an MVNO on the Verizon network. I pretty much narrowed it down to being an issue with the modem not working with CDMA. What I did was download the last Android 9 firmware and flashed just the modem (file starts with CP_) using Odin. After that, I rebooted it and voila! It connected.
Just thought i would give my experience as i just delt with this. i got my 10 update this morning nd let it update and apon a reboot i lost all mobile connection, a signal bar would show for a few seconds looking like it was trying to lock in a signal and it would go back to the ⌀ symbol. i tried flashing the android 9 modem from 2 different updates and neither fixed it. i just decided to order a new phone as i feel its time anyways. my next attempt will be to flash android 9 back using odin then just throw this phone up on craigslist
edit: odin successfully flashed back to android 9 and signal now works again. so if anyone has this issue you can try the method above of just flashing the modem and if that doesnt work you can go back to 9 and restore functionality of verizon mvno's

samsung a50 not connecting to VZW towers (red pocket)
My phone is doing the exact same thing and while I can appreciate how you resolved the issue it doesn't make much sense to me.
I use Red Pocket for my network. (Which uses Verizon towers - I use the CDMA Sim)
Before this major update to 10 my phone worked flawlessly. Now it won't connect to the network much like you guys have stated in this thread. Mine will connect intermittently for like 3 or 4 min tops and then get kicked off the tower and will actually not show any bars (Circle with a line through it) to show no service for about 10 or so minutes then restart the whole process.
I also have a work phone (2nd phone) that is directly tied to the verizon towers on the verizon network. If I take the sim out of that phone and put it in my samsung a50 the samsung a50 is happy and can make phone calls, send texts, and stays on the vzw towers with no disconnects.
If I take my red pocket sim card and place it in my work phone that phone also works just fine - send messages, make phone calls, and stays on the vzw towers with no disconnects. (work phone = iphoneXR - it's free, sue me)
Even though reverting the modem obviously fixes your issue I do not think that is the actual problem. It also doesn't seem that a third party carrier is being randomly booted off the towers, it seems to be a glitch with third party carriers using third party sims utilizing this new android 10 software that VZW towers do not like.
Which obviously points to an issue with Samsung's latest software not being compatible with third party carriers.
I can't seem to contact Samsung in a direct manner to resolve this issue as they want me to take it to a third party store to have it looked at. I spent 2 and half hours with tech support from red pocket and they came to the conclusion that VZW was doing "upgrades/maintenance" to their towers in my area. (whatever that means.
Any ideas on how I can contact Samsung directly to detail this issue to them? I really do not want to have to root my phone in order to use odin to set my modem back to version 9 as I'm hearing that doing so voids all kinds of implied warranties with the phone and it's only 6 months old.
Appreciate any help that you guys might be able to steer me towards.
Thanks.
Before this major update to 10 my phone worked flawlessly- They Told you the answer, Odin # 9 or if its under warranty take it back Good luck.
My phone (SM-A505U) wasn't even working on visible before android 10.
See my post at the end of this thread: https://forum.xda-developers.com/ga...official-firmware-t3955727/page2#post83845605
I have that problem too. Where I can download v9. I got the Odin.
Hi all, I'm new, so forgive me if this is in the wrong section.
I have two Note10+ I got from ATT both with clean IMEIs. I used a factory unlocking service where they send you the code to unlock the phone. The second phone I unlocked worked with no issues. The first one is what has problems. It unlocked however I had PIA VPN active when I unlocked it and it didn't shut down the same way as the other one.When I came back up, it now says Mobile network not available, gives me bars and then says emergency calls only, or flashes between the two.
Steps I've taken to troubleshoot:
Network and factory data resets multiple times
Changed the sim at T-Mobile, where it worked briefly but the boot up screen never changed from at
The phone is clean on every IMEI checker I have used. I got it working once for about a minute after i went to T-Mobile (it worked and then stopped again). Both phones are from the same ATT account
Mainly I want it to find the signal and download the carrier settings so it doesn't have the fugly AT&T bloatware.
I suspect it may have glitched because the pia app prevented it from shutting down and running some process. Is there a way to force it to "re-unlock" so to speak? Or do I now have an expensive paperweight?
