Ok so I have a SERIOUS problem. At times this Revolution will not send my texts....at other times I dont receive them. I have been able to solve this problem momentarily by turning the phone off and on again but I do not understand why this is happening. I am not in a 4G area all the time. I was assured by a representative that the 4 G phone would work fine in 3G. I am also having problems with Facebook loading. What can I do to resolve this issue??
