unlocking 4s not working
So I recently got a phone from my sister that used to be locked to bell. Her contract is done now and I want to unlock the phone and use it with rogers. I asked around and found a place to unlock my phone through a third party. Paid to have the hone unlocked but nothing. They are telling me the phone is unlocked but its not working with a rogers SIM.
Whats going on? Reset the phone and still not working.
