[Unlock] iPhone 5S AT&T

[rootz]

Hello,
I'm sorry for bringing up the same subject once more but i need to unlock an AT&T iPhone 5S and i would like to know what is actually the best way to do it.

R-SIM or IMEI Unlock?

I've heard a lot of people didn't manage to unlock via RSIM but another did so I don't know...

I don't mind the price/wait on IMEI unlock but what is the best (safety/price) site to do it?

if you have an AT&T account just file a request. if you are eligible they will unlock it for free.
