Activation needed averytime i switch SIM
I am a MAC user, i successfully unlocked my iPhone using independence / anysim. Yesterday, i wanted to test a friend's simcard on my iphone for seeing how it works with his provider, and the iPhone asked for activation and didnt work with that simcard. I had to activate again using independence.
My question is: is there any method to activate the iPhone for all simcards? because if in the future i sell my iPhone, if the customer is a dumb, i will have to activate the iPhone with his sim, and so so....
Thanks in advance!
