Most of the people I text on a regular basis have iMessage (blue) - but there is that one time that it will send it as a text (green) if it fails. I currently have the Unlimited Text plan with AT&T for $20/mo. I was thinking of removing this and just pay the pay-per-use ($0.20/sms). I know iMessage uses data, but if I remove the text plan will I still be able to received/send texts? Also, is there a chance (probably not) that iMessage counts as SMS to AT&T? Thanks.
