My Pantech Renue P6030 used to hold scores of text messages with no trouble...often hundreds. That capacity has slowly shrunk til now when, if I receive two short texts, I get the "messages full" warning and nothing I do will fix it. Deleting the two messages means I can only receive two more.

I checked 'My Stuff/Memory' and it tells me I have used 176.2MB or 293.3MB available. It gives this same number regardless of whether I have an SD Micro card installed or not.

I've never downloaded/installed/used any app... all I do is call or text with it. It's behaving as if there's a trash can somewhere still holding my deleted messages, eating the memory, but with 120MB of unused space available, what's the problem??
