Walmart now sells a SmartTalk phone. Cost of the phone is $30-$100, depending on how many features you want. 900 minutes a month is $30, unlimited with internet access is $45.
I have the cheapest ATT program now, no internet, and it is $72 a month. I'm going to SmartTalk next month. Supposed to have great coverage...
My dh has TracPhone, $30 every 90 days, then buy minutes. Approx 10 cents a minute. His isn't used every day so we buy 60 minutes for about 2 months.
My dd has Virgin wireless, another prepay. His averages $15 a month, again, he doesn't talk much at all.
The Smart Talk or maybe that's Straight Talk at Walmart looks like the best deal, my bff has it and swears it's fantastic. You just buy the preloaded card every month to activate.
