Are any of the ROMs in this thread sim unlocked? http://forum.xda-developers.com/showthread.php?t=935605
Or does the lock have nothing to do with the ROM itself?
The sim lock has nothing to do with the OS (actually, I think it has more to do with another part of the firmware like the radio, someone please correct me if I'm wrong). In order to sim unlock your phone, you have to get the imei # and contact your carrier for the sim unlock code.

Impossible.
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 unfortunately locked my unlocked S8+ international version while trying to flash the CSC for T-Mobile and now I can't use my sim card and I have no idea exactly where this phone originated from... am I screwed?
Hi .
I have bought a S8 locked to US Cellular on eBay, clean , not blacklisted and when I try a SIM card from my operator does not ask for unlock pin code and remains without registering on my network.
Does anyone know any website or any method to unlock It?
Many thanks in advance.

Does it have a unlock app in apps drawer or in settings. It may be unlocked. If ure sim works. WhT carrier you on.
Thanks for your answer.
I live in Portugal and I tried 2 different SIM cards. The phone shows in upper left screen the message "SIM blocked". I searched for an unlock app too but I can't find any like in T-Mobile phones I bought in the past.
US Cellular is a CDMA network provider whereas in Portugal you probably have only GSM networks.
I think you should look into this and investigate this issues as well.
Another info: I flashed with Odin with the latest USC official Rom from sammobile. Can be this the cause?
This is 950U version and therefore has the GSM frequencies as well.
Even if it was only cdma it would prompt to insert the network unlock code....
Any help?
WHen I put a sim card it appears a forbidden sign on the top, where I should see the network signal...
