I would switch. $111 vs $25 is a pretty big difference.Honestly, the 3G doesn't bother me, but I'm on wifi so often it really isn't a big deal. I'm able to look things up on the go, which is why I have data.
Is it the same numbers that consistently can't get through?For example, do you sometimes get through from your parents' landline, but other times it goes straight to voicemail? Or does it always go straight to voicemail from their number?
