Depending on the group, you can probably assume it; but you can't necessarily assume that everybody's carriers play nicely together. I'm on AT&T; I've learned that I can't reliably send messages to my father on Verizon. SMS may or may not get through; MMS pictures turn into a message telling him to go to their Web site to see them.
