Flashed s8 phone need help switching carrier - Android Q&A, Help & Troubleshooting

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!

[Q] Galaxy S2 cannot sim unlock even WITH carrier unlock code

Hi All,
I have a Galaxy S2 which is SIM locked to the '3' network in the UK. I have contacted the carrier and they have provided me with an unlock code. However, when I am prompted to insert the code when I put in a different SIM card the code is rejected. I've also tried running the GalaxySimUnlock app which also came up with the same code that I got from my carrier.
My phone was originally updated to stock ICS but I then flashed it to CM 9 and then MIUI. I initially tried the sim unlock with MIUI running. I've now returned the phone to the stock 3 image - it's currently running 4.1.2 baseband I9100NELS1.
Has anyone had this problem before or can you shed some light on what is going wrong - I thought if I contacted the carrier this would be simple!
Many thanks,
Steve
Make your PC's network is sold. You have tried many software unlocking by noon?
Hi duykhanh187,
I'm not sure quite what you mean! I have contacted my carrier and have got what they believe to be a good unlock code but it is not working.
Thank you for your reply,
Steve

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.

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.
