Group Messaging

Can you please provide a couple more details -

1. Is this in reference to SMS or iMessage or both?

2. Are the groups composed of non-iPhone users as well as iPhone users?

3. Settings - Messages - do you have MMS turned on?

4. Is this a recent development or have you recently changed carriers?

Thank you for the answers

It would almost seem that there is an issue with the text messaging "package" that you have with your carrier

I would call their tech support and request for someone specifically to look at your account provisioning on their end - we had another user where the carrier had failed to set up text messaging on their account

While you are at it - pick two iPhone wielding individuals from your contacts and try to text them in a group to see if a group message to just iPhone users is working - if yes - then it would point to my theory above - if you run into issues with that as well then we may be looking at a full restore to iron out the glitches

Please let us know
