Since June 17, 2011 Friday I can't not get incoming calls. Sprint customer service has reset my Epic 4 times, changed my #, everything you can imagine has been done to my phone. When you call my phone it says "your call can't not completed as dialed. I live in southern Louisiana, the calls that come in come from all over the US. 4th CS rep said a tower has been down since the 14 June & the problem was solved. I am so furious I'm ready to switch services. I'm waiting for a call from a cancer dr & I can't get calls.
Sorry to hear about your troubles getting calls. My 15 second snapshot diagnoses is that there is a routing issue, not anything wrong with your actual physical phone. One quick test would be to see if you can get a call from another Sprint phone in the same area as you. If you can, you likely have routing issue, which means that your calls aren't going to the right "address". If you can't then, something much stranger is going on.
These sort of things usually require a ticket to get resolved, as it requires work on the back end, but I'll be more than happy to check things out. I will private message you so you can respond with your information so I can investigate this for you.
