Does this phone send and receive group text messages?

I am unable to send or receive MMS group messaging on this phone. I tried to download a different messaging app, but it still won't let me send. It says to try inserting a SIM, but his phone does not support that. I can still send through my old app, but it sends as separate messages, not as part of the group thread. The messages I receive come as seperate messages, and not as part of a thread. Anyone know how to solve this?
