My daughter is on her second asurion. It worked good for a few days and now it wont make or recieve calls. It also has trouble sending texts sometimes and phone has to be restarted. I have seen others post this problem, but nothing about a fix if there was one. The usual batt pull did no good. Now, should I do yet another asurion replacement for the rezound, or insist on another type of phone? My rezound has been good for the most part, but im getting sick of dealing with hers.
