I've been noticing that texts I'm getting (multimedia like pics and what not) aren't showing up in my inbox. Like my phone will light up, but I won't get notified of anything showing up and nothing will be there in my inbox, even after someone tells me they sent me something. I've tried powering down my phone, removing the battery and all of that--but nothing seems to work. It's an on and off thing, but it's so frequent. Does anyone have ideas as to what's going on? I have a Nokia 6790 (and I guess my provider is AT&T) and I've had the phone for a few years. I plan on upgrading eventually, but is there anything I can do to resolve the problem until then?
