No roaming = StaySmart by GoingNowhere
This month marks my 1st anniversary with T-Mo on their $30/mo flat cost for 1500mins voice/text (each in or out msg = 1min) + 3MB data + national roaming. Usage is clustered in the 900-1200 mins range with one month of the last eleven at 1390 and three months sub 900. I don't use data and text is disabled at the net level = voice only for me.
Would have liked to switched to GoSmart at $30 but the no roam = stay with what I have.
