Regarding the $25/month plan with unlimited text, email, data, and web with 300 anytime minutes...how in the heck do you make the 300 minutes stretch every month? Or do most of you just text, email, web, data and not really talk on the phone much? I have google voice but it uses voice minutes. I think I read something about sipdroid and using wifi for calls...just seems like $25/month is a really popular plan and I think a lot of you guys have found ways to get more bang for your buck with this plan...just curious how. Thanks in advance.
