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.
I would like to ask @wujke as he is from the same country (and maybe same network as i am) one question.My carrier (from which i bought this device on contract) doesnt support official updates above kitkat.As i updated this phone to lollipop (different modem and firmware) is it possible that i broke a sim lock from my carrier.last week i was abroad and i used sim card from that country with no problem.Since i dont own any other sim cards i would be grateful if somebody could answer this question.Thanks in advance
Everything is possible, maybe it wasn't locked at all. In Telenor I've seen everything, from unlocked phones to locked without possibility to unlock bootloader.
I received at&t S7 phone at work few month ago, I have never put in the sim card into the phone, now I want to sim unlock to use with Tmobile network, try to unlock with code purchase online but they can't find IMEI code... is there other way to sim unlock ,
Thanks
I recently bought an unlocked sm-g930a. Do you know if updating with the new at&t 7.0 firmware will lock the sim to at&t again?
Best Regards
Hello,
I just acquired a new 'Huawei Ascend XT' phone which is sim locked to AT&T. I am currently in the process of unlocking the boot loader and rooting the phone.
I was wondering is there any tool available to Carrier / imei unlock this phone after I have rooted it (or may be even befor rooting it)?
Thanks.
I'm fairly certain you just need to change the apn settings manually.. need to do something weird to bring up the option to add/edit, believe it's holding down the tasks button
Without being carrier unlocked, the phone can only be used on AT&T Prepaid, AT&T, or AT&T based MVNOs. These days AT&T won't give you an unlock code unless you use the phone on AT&T Prepaid for 6 months. You can check eBay to see if any unlockers will sell you an unlock code for a few bucks. Only buy from sellers who have a money back guarantee if their unlock code fails.

Bought 2nd-Hand
I would like to ask if there is any way to carrier unlock. I bought this phone for 20$ on offer up. But when I contacted at&t to request unlock they said it has to be used for 6 months. For me that does not work, as I am already with tMobile and bought the XT for a second phone because of the large device support. I actually love the phone, but as is it is just sitting around. If anyone has or has heard of a way to accomplish an unlock please p.m. Me.or answer in forum. Thanks in advance.
Ps. phone is already bootloader unlocked and rooted with magisk 14.0. And latest TwRP.
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
