I recently changed my mobile carrier to Xfinity Mobile. Last 2 weeks I constantly see "Call failed" message on phone whenever I try to receive the call. My spouse and one other friend is facing the same issue. This happens on XM wifi as well as regular network. Most times I need to rely on WhatsApp calling while calling other xfinity lines as we can't pick up each other's calls :). We use iPhone 6 & 6s. Any help here?
