If I remove my SIM card, will it erase anything off my phone or change any of me setting? What affect will it have?
I can text everyone but one of my friends who does not have an iphone. She can send me messages but she doesn't recieve any of my texts. I can text other non iPhones fine with no problem and I have already turned my iMessage off. Will removing my SIM card help?
iPhone 4S, iOS 7.0.1
