How to receive text messages on iphone without cellular data activated?

I have the iPhone 5, and the lowest size cellular data plan. I want to be able to receive all these group text messages without having to activate my celluar data plan, and when I do activate my plan, I want to fix my phone from updating with 60 new messages from the last night that never reached me because my plan was off. =/ Can I do this? I run with At&t.

During group messages you are more than likely using iMessage, which requires data.So, a quick solution would be to turn on Wi-Fi. If that's not available, turn off iMessages(Check sources).
