With all of the unlimited everything plans dominating the world of prepaid currently, it's easy to forget about the smaller offerings ideally suited for those looking for appetizers instead of the all-you-can-eat buffet. AT&T's announced a new monthly package that may fare well with the nibblers, doling out 250 anytime minutes and unlimited messaging for $25 beginning on September 18th. Two other prepaid services are launching the same day: a $10 international long distance package that includes 250 minutes within a period of 30 days, and per-use roaming in Canada which can be had for $.39 per minute and $.25 per message
