I didnt know where else to post this but I was looking at AT&T's go phones and they had a plan that had unlimited mobile to mobile minutes. Can someone please tell me what this means?

It probably means making calls from your mobile to other mobiles.

so does that mean unlimited text messaging?

If it doesnt state so, then probably not.

OK well are there any pre-paid phones that have unlimited text messaging?

No idea, i only use pay as you go as i don't have a credit or debit card.
