Northern Illinois | I just started having a similar problem. I have a Iphone 5s on AT&T. One of the guys that has a older phone on sprint, I always used the contact on my Sync to call him and also dialed. When I call him I get the same message. I will try many times and finally the call will go thru. It almost seems it will do that if he doesn't answer. It wont send me thru to voicemail. And of coarse I am the only he claims to have this problem |
