I have an HTC Thunderbolt. Have never had any problem with it before, have sent and received thousands of texts without a hitch! However, over the past four or five days I have discovered that I am not receiving text messages that others send. They can receive texts from me, but I do not receive their replies. I am missing a lot of important texts from work/family. Other's devices show that their texts were succesfully sent, but I do not receive them. Helphelphelp!!!
