Sim not valid
I erased setting in I phone and then putting my sim card again in Apple iphone and now error is occurred.
It is written here that " the sim card that you currently have installed in this iphone is from a service provider that is not supported under the activation policy that is currently asigned by the actiavation server. This is not a hardware issue with the iPhone. Please insert another sim card from a suported service provider or request that this iphone is unlocked by your service provider. please contact apple for more information".
