Now that my phone no longer displays my balance, I have been running out of minutes without knowing. It would be really nice if I could get some sort of warning that I'm running low. I also think it's a bit obnoxious to be denying incoming callers when I don't even know there's a problem. It would be good if calls could go to my voicemail instead.
Is a text message when I'm getting low really that difficult. For that matter, how about a text message when I run out of minutes telling me to refill.
