Looks like I'm another one not receiving calls. All been fine for months, lately people calling me and getting the engaged tone, or a 3 tone continuous burst. Also when I try to make a call, it hangs after no more than 5 seconds. This is NOT happening every single time, but most of the time.
Also, I cannot verify my TSB account. It's not my handset, tried in 2 other androids same result.
