[Q] Will a factory reset erase my SIM unlock?

Hello, just bought a T mobile Sensation 4G from ebay, it came SIM unlocked.
I really need this phone to stay unlocked, so my question is, is it safe to perform a factory reset without losing my unlock? Is there even anything that can possibly remove my unlock? such as rooting and installing custom roms.
Any answers are highly appreciated.
Sim unlock has nothing to do with rom or factory reset so you should be good

Dear All,
I am new to android phone. I have SFR(ZTE) Staraddict. It is unlocked and I want to remove google account already entered in it as it is not mine. I search the internet and only find that the factory reset can only do that. Since it is unlocked I am not sure whether I can factory reset it as it will result in locking the phone (As far as I know). If there is another option or something I can do. Kindly help
Thank You

Thank you. But how can I carrear unlock it again. I don't have any device to unlock staraddict. Can any software be used for unlocking it or I need hardware of some sort.

If it is carrier unlocked it will still be that way after a factory reset.

I9300 Sim Locked After Manual Upgrade

Hi guys, I am newbie @ xda. I am having trouble with my I9300 and I could not find something useful on internet since months.
My I9300 was factory unlocked. I made a mistake while manual upgrading, I install Spain-Movistar sim locked 4.1.2 on my phone. After it my phone became simlocked. I could not solve this problem and I took it to a technician and I paid him. He does not say what he done on my phone and he unlocked it.
Now it is running rooted 4.1.2. He can not upgrade the phone to 4.3 because he can not unlock it.
Please help me I want my unlocked phone again and I want to upgrade it manually in future.
Thanks
Note: I manually upgrade to 4.3 but it locked again and I took it to technician, he downgrade and unlocked it same way.

Fresh Custom Unlocked S7 (930P)...can it be updated?

I bought a custom unlocked s7 from ebay and it is the sprint model (930p) and i am using a tmobile sim card in it. Current software is PC5 and i do believe the software used to unlock it is custom because of the unlock padlock during boot. I was interested in updating my phone to benefit from bug fixes. It is the snapdragon 820 model and upon factory reset the same custom software was still on it.
My question is this: could i update my s7 via a ROM upload without ruining the unlocked feature of the phone.
Any help is appreciated! thanks!

H83020i_un ROM and factory data reset

Im wondering Is it safe to perform factory data reset with H83020i_un ROM, or more precisely, can that result with sim lock on T-Mobile ?
H83020i_un ROM is H830 variant that was sold through Ebay as unlocked phone, but it is actually unlocked by modified ROM, and any update or change of ROM would lock it.
