Help Can't Send Group Messages but Able to Receive Them


Hi All,

I currently have a Nexus 4, using Chomp SMS as my texting application. I am able to send and receive picture messages and I am also able to receive group messages. However, I am unable to send out group messages.

For example: I am in a group message containing 7 different people. I am able to receive all of their messages perfectly fine. When I send my response to them, I send 7 separate messages and they each receive it as a regular text.

My mobile carrier is T-Mobile.

Can anyone help me fix my phone so that I can send a single group message?
