Once you sim-unlock your phone it will stay that way no matter what you flash. The only time the sim gets locked is if you get a new phone.

I have SIM unlocked 3125 but it has really old OS, so I would like to upgrade. Will flashing Cingular ROM make my phone SIM-locked again? I have a feeling it would but still hoping to avoid having to pay for unlocking already unlocked phone
PS. Sorry if it is an obvious question - I did use search.

I have a Rogers branded x10 that I'm currently using with Fido. I'm interested in updating to the newest firmware, but I want to ensure that I don't lose my SIM unlock in the process.
Can someone please confirm?
No it won't.
I presume that you have unlocked it by code.

Thanks for the quick reply.
Yes it's by code, I sent my IMEI to this website and they provided me with a code.
once you are unlocked it wont relock, even if you root or flash different roms

hi, I recently take my x10 to a guy to unlock it, now it has stock firmware whit eclair, my doubt is because I don't know what method used this guy who unlocked the phone, so if it was a different from code method, can it be locked again?
sorry for my english

Hmmm......well I'm not too sure but I think you should ask him. But if you use flashtools to unlock it it should be fine according to me. But ask him or wait for someone who knows for sure.

there are two types of unlock.
1) sim unlocking to use different network carriers
2) bootloader unlocking - to use different custom kernel nd roms for unlocked bootloader
as for sim unlocking, once you do it, it will not relock whatever you do
if you are planning to unlock your bootloader be sure that you have SETOOL sim certificate or SEMC sim certificate as stated in this guide: http://forum.xda-developers.com/showpost.php?p=19685019&postcount=7
Well my case is like this!
I'm looking to buy a motorola photon online,it was on spring and it suposed to be unlocked for every carrier. i'm from mexico, we use telcel.
The motorola photon only comes with GB android, and i've always like to modify my phones with roms, root, etcs.
Before i do any transaction i'd like to know if i can instal ICS roms or any other cooked roms without loosing the unlocked carrier?.
I know that theres a lot of ways on unlocking carriers like imei and other programs, but if i loose it, the unlocking is gonna cost me something?
Unlocking the bootloader is only to install roms? or i can do an unlocking carrier by unlocking the bootloader? it cost me anything?
This method by Lokifish Marz is to unlock bootloader or carrier???

unlocking bootloader and installing a custom rom will not make you lose sim unlock

sim unlocking is usually only possible via SOLD sim unlock codes so yes, if you need to sim unlock you have to pay

unlocking the bootloader is done to be able to flash custom recovery, custom ROMs and custom Kernels, improving the performance and usability of your device

bootloader unlocking and carrier unlocking are not related. bootloader unlocking can be done for free by yourself with the help of the info here in XDA. SIM unlocking requires a code you usually have to buy.

losing 4G shouldn't be of much concern to you. Telcel doesn't use WIMAX 4G so you wouldn't have had any use to it anyway.

if the cell is 2.3.5 already it cannot be unlocked and you CANNOT downgrade it because you risk HARD brick
The sim is only locked in US.
All other sims work.
But stuck on GB. Even if you could flash ICS the photons kernel is so old the video doesn't work well.

Flashing a rom or RUU won't remove s-off, as long as it's s-off, doesn't matter if the bootloader is locked or not.

I don't know of any way to lock the sim, I'll have to leave it up to the GSM experts to answer.
I suggest you update your subject with that question instead of just a Q...
The Rezound does not have SIM lock... Never did. no amount of flashing anything will lock it.

I have got unlock code from ATT to unlock my device to use the phone out side ATT network. Right now I am on lollipop ROM and when I insert a different sim and enter the code it says cannot unlock.
Do I need to be on stock rom to use the unlock code?
TIA.

Yes, you need to unlock the device with the stock rom installed.

I don't know your particular setup but if you are on AT&T then use clsA's Stock Rom Reset.

I had ARHD downloaded on my phone, so installed it and successfully unlocked my phone. So root doesnt matter for applying unlock code.
Thanks for guiding me correctly..

A little bit late to all this I just got the M7 . I did not think to unlock before flashing and rooting. So in order to unlock the carrier restriction I have to be back on stock and then enter the code that AT&T gives me?
