I did some searching and couldn't find anything like what I am experiencing. I am on a prepaid account and when I make calls, the phone does not ring. I can hear the person on the other end saying hello over an over. The person on the other end says that they can't hear me for a few seconds after they answer the call. I have tried two different phones and they both do the same thing. One is a Motorola V551 and the other one is an unlocked pebl. Could this be an issue with the SIM card? Any help is appreciated.
