I was using Tmobile unlimited text only plan for $15mo. Sure I could make calls for $.10min. Then I discovered there are a lot more MVNO options out there. So I decided to test out H2Owireless (an AT&T reseller).
I turned off iMessage. It didnt seem to send any messages for me without a data plan. Then I found the MMS fix (see below), and it resolved the issue. However, H2O charges more for MMS ($.10), and a text message is $.05.
