For years, most prepaid cell phone providers charged a flat per-minute rate for calling, usually without a monthly service fee, for those who didn’t want or couldn’t afford a traditional postpaid calling plan that came with a large bucket of calling minutes.

But now prepaid cell phone providers are increasingly announcing new bundled service pricing for prepaid users that would be familiar to any cell phone user with a two-year contract.

AT&T today announced a new plan (available Sept. 18) for its prepaid GoPhone customers that bundles 250 voice minutes with unlimited texting for $25 a month.  It joins AT&T’s $50 unlimited talk, text, and web plan for GoPhone customers, without any contract commitment.

AT&T also announced a new International Long Distance add-on package for prepaid customers.  For $10 a month, customers get 250 minutes of calling to over 50 countries, good for 30 days.

GoPhone customers can also now roam with their prepaid phones in Canada at special roaming rates, according to AT&T:

• Voice – $.39 per minute (no surcharges)
• Text – $.25 per message sent, $.20 per message received
