Hello all. Kindly support me with possible solution on network issue with my unlocked LG Velvet. Once I switch it on, it first brings network but after like 2 minutes, network goes off the phone until I restart and still repeats the same issue.
Mine is AT&T. And recently went to T-mobile and my data turns on and off. My phone is unlocked at&t.

Mobile Network Type- Unknown
Service State- Out of Service
Mobile Network State- Disconnected
My IMEI still shows up and I can connect to WIFI and bluetooth. The only problem is I can't get a signal, not 2G or 3G (even LTE)
This started happening out of nowhere, I tried taking out the sim, factory resetting, wiping caches, changing the APNs, restarting the phone, and I even put the sim in a new phone (It got signal).
If anyone has any ideas I'm all ears! What's the point of this amazing phone if I can't call people with it?
How long did you have the phone before this happened? Did you dial *#*#4636#*#* to check the phone info and change the network type?
I had a similar issue, but I think mine was a lot worse due to a dirty flash. I ended up having to do a fastboot recovery to restore it to factory.

What service are you with? I had this same exact issue a week ago with an LG G2. My Sim card would work in my Nexus 5 but wouldn't work in the G2.
After numerous factory resets I eventually called Metro PCS (my carrier) and I was told that whenever I put my Sim Card into a new phone I must always contact them and give them the new IMEI # so that the phone can work.
The Metro PCS rep claimed that they have a feature that disables the Sim from working in an unauthorized phone. I guess its to help with theft.

If you have a method of fixing this please share.

I know this is really OLD!!!!
but i just had the same issue today
with a NEXUS 5 running stock marshmallo 6.0.1 with the latest patches
, and yes... is not the phone is the carrier
MetroPCS do IMEI lookup
i had another phone before the NEXUS 5
so it is no just matter of swapping the SIM card from one phone to the other
you need to call CS and you told them that your phone is not registering on the network
and that you just swapped phones
So they ask you for the IMEI of the "new" phone
and your SIM card #
you reboot your cell
and VOILA!
now the phone registers in the network
Yes, Metro do IMEI authentication
Hello Everyone,
Recently I came back from trip to USA. Everything was working fine, I used Wind's roaming in USA. Ever since I came back to Canada, my phone is struggling to connect to Wind Home network. It almost always connects to Wind Away (roaming) even when I'm in the coverage zone. I tried a new SIM card, factory reset, *#*#4636#*#* steps and I'm still stuck. Eventually it connects to Home network after 1 hr but when I lose the signals (subway tunnel, basement), the phone is back to Wind Away and stuck again.
I tried Koodo and Virgin mobile SIM on OPO and they work fine, however when I put my brother's Wind SIM (which was not used in USA at all), the phone doesn't connect to WIND Network. The same SIM on LG G2 locked on WIND works fine. The provider says that they have no issues from their side regarding the IMEI and all that.
Can someone please help me with this frustrating problem? I'm running CM12.1 (currently stock state) and International OPO. Thank you!
I have the exact problem on Wind with my oneplus one. Went to Lac la Biche for a few days and now I'm back in Edmonton it's stuck on wind away.
So I recently bought a Sprint HTC U11 off ebay, and at first it didn't work at all with my T-Mobile SIM, all it showed was a full strength signal with a capital R next to the signal bar. I called Sprint and they confirmed it's unlocked, although they said it may still be tied in some way to the original owners account, which could potentially cause problems.
I managed to get it working on LTE, by going into testing mode (*#*#4636#*#*) and setting the network to CDMA/LTE only, but with this setting I can only use Data, no Calls or Text. It is also has Sprint as the provider instead of T-Mobile, and I can't switch on VoLTE (greyed out in the Testing menu).
I tested it with some of the other settings, but anything that turns on GSM makes it glitch out, connect for only a few seconds to either T-Mobile or U.S Cellular (a provider I automatically roam on where I live), and then disconnect and refuse to reconnect to anything until I switch back to CDMA/LTE and reboot.
Is this a common problem with the Sprint version of this phone? Are there any fixes for it? The phone is currently not rooted or modified in any way, and is running Android 8.0, Software version 2.33.651.10.
Thanks for any help.

I don't know what else to do without returning the phone under warranty or doing a hard reset first to see if that fixes the problem. I bought a Xiaomi Redmi Note 8T in July 2020 and the phone can only connect to a 2G network (Edge's E is at the top instead of 4G in one). I have not changed anything and am afraid that it is broken in my mobile if possible. I am using the Google products and not the installed Mi products, I have Android 10 with Miui 12.0.3 (the last one).
What I've already tried: I've been in contact with T-Mobile because my son has the exact same phone and subscription. It does have 4G just like I did before. All settings are the same, in terms of T-mobile server, preference for LTE networks is set, etc. In the Settings everything is the same. According to T-mobile, there are no problems with the network. I have done another system update (to Miui 12.0.3). Mobile data turned on and off. Airplane mode and reboot and back on. APN reset and then phone started did not help either. When selecting network automatically, I turned off and manually search, but then the mobile only finds 2G networks.
Then a clear moment and see if it is the SIM card, so my SIM card in my husband's iPhone and yes it just indicated connected to 4G. Then my husband's SIM card in my Xiaomi and then it only indicated E again. With my son Xiaomi have done the same but again 4G on his and with his SIM card Edge in my phone again. So I'm sure it's the problem with my phone. Who else knows what I can do? I will try after a hard reset the same Edge network will still remains or if 4G works again. All responses welcome!
I think that there is something wrong with the GSM module because I tried *#*#4636#*#* and then tried several settings but it still give Edge even if I force the network to LTE only. If I give in LTE only it says: IWLAN no roaming, only emergency calls.
Hello!! I'm new here! I hope I'm posting this in the right place. I have a TCL 30 XE 5G (T767W) from Metro by T-Mobile and I had it sim unlocked by an eBay seller who had me hook it up to my PC via USB. The settings menu says it's still locked but it does accept sims from other carriers so I think it's unlocked. The problem is that it won't find any service at all with any sim other than the original Metro sim unless I set it to 2G only mode. Even selecting my service provider from the available network list doesn't work. The only way I can get the phone to find service is to force it to connect to 2G then change the network mode to LTE and then finally set it to 5G and that doesn't always work either and even when it does it's only a matter of time before it randomly disconnects and is left forever searching for service but never reconnecting until I set it back to 2G only mode again. All this is happening in a city with great T-Mobile coverage and all of the sims I've tried run on the T-Mobile network. The only sim that works without any fuss is the Metro sim even after the phone was unlocked. I'm using the phone on a T-Mobile MVNO now but it always disconnects sooner or later. I don't understand how a new phone can't automatically find an LTE or 5G network without first connecting to 2G and it doesn't find that either unless it's set to 2G only mode. Aside from the obvious inconvenience this causes, T-Mobile plans to shut down their 2G network soon at which point this phone won't be able to find service. Has anyone else run into this problem? I have two of these phones both are doing the same thing. Did something go wrong with the unlock? Is it a software issue? I tried asking my carrier for help but they can't figure it out either. I appreciate any help or info anyone here can offer. Sorry for the long post.
i suggest taking into a service and getting it there unlocked. perhaps your method prove faulty.
