group chat receiving but not sending

[fnitni]

trying to set up a group chat with my kids. I can receive group chat messages but my responses seem to get hung up in "sending" mode and eventually fail. Not sure if it is the public mobile network or if it is my phone, Unihetrz Atom L or if there are some settings that I have incorrect...anyone have any thoughts?

Can you use mobile data or have you previously? Have you previously been able to send MMS (picture texts)? Group chat (RCS) requires mobile data. Do you have data available in your account? You may need to edit your APN. Check it and compare it to the following APN. Public Mobile has a few variations of their APN but this should work if perhaps your phone has defaulted to telus.

@fnitni   are you sure you are sending via MMS or RCS? 

Make sure "MMS Messaging" is enabled in Message settings.  Also, make sure Mobile Data is turned on.
