I haven't been able to find any solid information on SIM unlocking this phone, so I'm asking here. Back on Verizon, unlocking a global phone didn't seem to help much, as it still didnt work on other carriers (such as when travelling to India). Will the S4 (originally on AT&T) when SIM unlocked work?
Hi! first poster here.
I've just got this phone wich was recently unlocked from TELCEL MEX carrier. The weird thing here is that the phone work flawlessly with any domestic carrier sim cards, but not with my US T-Mobile sim card.
I've test this T-mobile sim card with other unlocked phones (Galaxy S4 i9500 and Alcatel Pop) here in México without problem, but in the S4 above mentioned asks for sim unlock code.
The cell phone is SGH-I337M with KitKat 4.4.2. and firmware CSC code TCE
Thank you very much in advance!
This may be relevant or not.
My previous phone was an HTC Desire S on O2UK.
O2UK give you a free unlock on all contract phones after 6 months and send a code by email to you.
Any time I tried changing sims to a different carrier it asked for the unlock code, except when it was Tesco Mobile UK.
It may be that the original carrier requires you to input the unlock code for anything other than certain providers.
I tried to get an unlock code for my I9505 LTE but they said it was factory unlocked so can't speak about the phone specifically but with the Desire S, also on O2UK, had a similar issue.
I've got the pin code
Thanks for your input, sure it's relevant.
I have the unlock code for the T-mobile sim card, but of course it's not recognized by the phone (or sim card?)
In the other phones tested the process was straight forward, just inserted sim, boot up and voilá.
Went to the Telcel's service center but the person there confirmed that it's unlocked.
I'ven reading about a "Regional Lock" of some Samsung devices, but i realy can tell if this the case.
Anybody else having this kind of issue?
Region locking I don't believe has anything to do with this. When the phone was unlocked, the region locking should also have been removed.

Hello fellas, I have the LG V20 AT&T phone and I want to be able to use the sim of any network carrier of my choosing and I’ve been told that it's next to impossible to unlock AT&T phones unless you have the stock locked Rom and if I will flash unlocked Rom the phone will be sim free. Would that be correct If that is correct, my question is: Does anyone have unlocked Rom from this phone? At this moment when I insert different carrier sim the phone ask for 8 digit sim network unlock put code. any guide for it or someone with the knowledge to do it or someone pointing towards the right direction would be greatly appreciated!

From my understanding, and at least on Tmobile, you have to ask the carrier for the sim unlock code. Your phone has to be paid off if you bought the phone through the carrier. This is independent of the rom used. Check this out: https://www.att.com/deviceunlock/#/

Since you are being prompted for a actual unlock code.you do infact have at&t and NOT t mobile device with their garbage unlock app and process.simply look for a unlock code for a "lg v20 h910" or "lg v20 at&t unlock "on ebay.all the other cell unlock sites are a rip off. Codes are pretty cheap like 2 bux or so.now if you had a t mobile device you would have had to jump through a lot of hoops to get it unlocked.luckily you dont.

it should ask for code automatically after rebooting with different carrier sim, if not - then you should use network unlock app for connecting to server and entering code
what is the difference between lg v20 sim unlock code and network unlock code? as I understand sim unlock code is 4 digit and network unlock code is 8 digit, correct?

how to choose the right model for MetroPCS carrier? as I know they using 2,4 and 14 LTE bands
is it possible to unlock lg v20 sprint phone with "BAD ESN" ?
Unlock code lg v20
Can you please share the site. I am trying to unlock my LG V20 and need help please.
Thanks
Any lg simunlock.com will be deleted as spam
To unlock an LG V20 (lgv20) on AT&T (att) without another network sim:
Dial *#06# on your device to find your IMEI
Get your unlock pin from att.com/deviceunlock
Dial or paste: 2945#*910#
A menu will popup. Choose network lock. Enter the unlock code AT&T gave you.
The phone will restart and be unlocked.
So I got to the unlock screen by entering:
2945#*910#
The 910 is the model number. My phone's Settings > System > About > Hardware Info lists my phone as an LG-H910
So if you're on another network, chances are you could use your model number to get through.
I bought this supposedly T-Mobile H918 on ebay. It says it works with T-mobile, Lycamobile, UltraMobile, Simplemobile. I figured (assumed (mistake)) the phone was unlocked. Tried to use a Freedompop gsm sim, no go. Went over to T-mobile they said it was NOT in database, couldn't unlock a phone not in database.but rep put his Tmobile sim in and it worked. I decided to order a T-mobile sim online for $10. In the meantime I went online looking for a LG IMEI checker. It turns out the phone is an Israeli H990. I guess someone flashed the T-mobile H918 on it. The IMEi is clear according to swappa and others. Should I send it back? It had H918 10K on it and I flashed back to 10J and rooted. I like the phone, but is it possible that it could get blocked down the line? If it's clear and can be used on different T-mobile MVNOs is it unlocked? I plugged IMEI into AT&T checker and it said something like, it's clear, we just need to get the right sim. Any help or info or ideas appreciated, Thanks Johnm

If you were able to root it, then its probably a database mismatch. The gsm simcards usually pose problem to T-Mobile's android handsets due to UICC activation (or UICC unlocking).
A crossflashed phone is hardbricked the moment u unlock its bootloader and load a custom recovery on it. (Had my chinese fake G3/G2 moments back in the days). Your phone is fine if you rooted it and its working right out of the box.
Two things that dont work if u modify the system of LG phones is RIL and the abnormal screen behavior. For your case, both work. I'm from Pakistan but I often end up having unlocked phones from American carriers. Right now I have Samsung Tab A which is from T-Mobile and UICC activation doesnt make my LTE Sim work on it. With T-Mobile its kinda common to end up into an "invalid sim card" error when u try to use a non-T variant.

Wow Thanks, this story is getting more interesting. I appreciate you relating your crossflashing experience. I guess I'll try to get some different gsm sims to try. Thanks, take care, johnm
I just upgraded from a LG V35 to a Galaxy S20+. So the V35 has no sim card now but still connects to the internet over wifi. The V35 is the unlocked model V350ULM still running Android 9. Android 10 should be here soon based on what I have read online. Will the update go through normally considering the V35 is no longer registered to a cell carrier? The V35 was on Consumer Cellular previously with a T-Mobile sim card, not sure if this last piece of info matters.

If you haven't installed a sim card,as far as i know,it is not going to get an update.
Otherwise,you have to carrier unlock it and after you can update it manually when android 10 ULM kdz will be available.
P.S..you have a p.m.
