I got my iPhone 5s two days ago. I was able to call my father yesterday and it was all fine. I tried making a call today and it wouldn't go through. I can receive calls and send and receive texts and do all the other phone things except now I can't make a call. It tells me "We're sorry, we are currently unable to authenticate your phone" and then to try again or dial #8899. I've tried numerous times and numerous contacts and it still isn't working; when I called #8899 there were no representatives available. I've seen similar posts to this but none of them have helped me fix this problem. If anyone could help me figure out what to do, I will be so grateful. ¡Gracias!
