i have an unlocked blackberry 10 will reloading software lock it again?

I was running into problems like slow app loading android runtime crashing etc.I tired a a security wipe but it gets stuck at 96-97% even after battery pulls.
My phone is not factory unlocked(can't load BBM-Can't connect to BB services).This is how i figured that it isn't.
I am considering reloading the software via link or autoloader but i don't want the phone to get locked again.
What option do i have now?
Thanks.

No, the phone won't get SIM locked again.

Reloading seems like my only option now.I will try it.Hope you are correct.Will reply with the outcome later

Reloading the OS has nothing to do with carrier locking/unloching.
