Just tried this on my XA2 and I can send a single SMS to multiple recipients where the message goes to the recipients individually. I toggle-off the option to ‘Send as group message Recipients and replies will be visible to everyone’
If I send as a group message, the message fails to send. I believe group messages are sent as MMS and historically I have never had much success with MMS on this device although I remember getting one to send under 0.14-q. Fortunately I don’t require these services to work anyway!
