R-SIM Pro does it work with iOS 9.3 ?
 

Hi, i have an iphone 4s iOS 9.3 and R-SIM 9 PRO . I use it in Argentina with carrier code 7220104 and it doesnt work. I dont have a signal, sometimes i get 1 bar and then nothing.
THe weird thing is that last month i went to Ecuador and i had a full signal and i didnt reconfigure it. People could call me and i could make calls to my argentinean number.

Any explanations?

Cheers
Julian
