No group messaging option on iPhone

[ClaireGra_70205]

I can't  find group messaging as an option on my iphone. It was suggested that it might be to do with my carrier ie Smarty. I have no problem receiving messages from individuals  in the group, or sending them,  but cannot see the group and cannot see a way to change that. Any ideas? 

Thanks

What messaging app are you using?  If it’s iMessage you can follow the instructions on this link. https://support.apple.com/en-gb/HT202724

Not sure if this is helpful for you.

On iPhone, you can add more recipients when you want to send a message. This effectively forms a group. You start by entering Tom, then add **bleep** and finally Harry and then there is a 'group' of the four of you for any messages sent on that thread.
