Just got brand new Razr Maxx on Saturday, and twice this week I've had no data signal. Phone appears to be working, and email, but no Internet connection for anything else. Phone indicates i have 4GLTRE and at least 3 bars but i can't get anything. (no facebook, no browser, no updates, etc.). I've noticed other people on here complaining of same thing several weeks, but cant' find solution. Is there one? Or did i trade in an old Palm Pre, that worked fine and had data signal (though slow) all the time, for this dud?
