What is SIM network unlock PIN?

Hi guys, recently i bought a used galaxy s2 from a dealer. I think it should be the international unlocked set. I updated to firmware to the latest version and formatted the phone. After that this sim network unlock pin appears. The phone is usable but no network. Anybody can help explain to me what is this thing and how to solve it. Any help would be appreciated.

[Q] Galaxy i9300 || Unable to Network/SIM Unlock

I have seen a number of questions that are simular to this, but I have not been abe to find one that is like mine, therefore I am posting this.
I have a Galaxy S3 International version that was bought from Digicel Jamaica. It is completely paid for, I called Digicel to ask the for a unlock code. they informed me that they do not do that and I would have to go and get it professionally unlocked. the reason I want it unlocked is that I not longer live in Jamaica, but now live in the US and would like to use the phone for the next couple of months until I can get a phone on contract.
I have tried everything I have seen on this site, including getting a unlock key. nothing works.
I upgraded the phone 4.3 sometime ago and have also rooted it in the pass.
Whenever I try the *#197328640# , after [6] Network Lock I get no menu options see .
PLEASE HELP ME :crying: :crying: :crying: :crying:
I have also tried using RegionLock Away and Galaxsim Unlock, both tell me my phone is unlocked, but I still can't use another sim in the phone.
PS. I am using a T-Mobile Sim from straight talk
You can't region unlock on 4.3 at all, sim lock is possible but only if you buy a valid code -there is no other way and your posts are identical to hundreds of others.

I have a valid code, but the SIM unlock doesn't work with the code. I have tried everything I have seen online, downgraded to 4.1.1, replaced the stock 4.1.2 that came with the phone.... nothing works

LG V10 SIM Locked - Not For Sale Unit

Hi All,
I bought a LG V10 T-Mobile thru buy& sell online and didn't realized that it still Network Unlocked. I cannot use it to other Network provider and I am very frustrated already. I already try using several unlocking sites but the codes for my IMEI are always cannot be calculated. I'm not sure if this unit is just a demo and cannot be unlock. I also check my IMEI number to T-Mobile IMEI Checker from their site but unable to verify my number. Done also chatting with one of T Mobile support but they cannot also help me to unlock my phone. They said I need to by a T Mobile SIM Card but it is not possible because I'm from the Philippines. There is also a note engraved to my unit saying "Not for Sale H960A Rev 1.0".
Please help me if there's still a way to unlock the network of my phone.
Thank you.

Flashed s8 phone need help switching carrier

Hi everyone,
I currently have an s8 which I flashed to have a service code of xaa. This worked great with my Roger's plan that I use here in canada. But I recently switched to virgin mobile and I get an error that says: "Network locked sim card detected."
How do I fix this error? Do I need to flash my g950u to a canadian service code?
Anything helps! Thank you!
