To initiate an SMS session with multiple numbers, you would have to enter those numbers, separating them with a comma. There is however an easier way of doing this by using contact groups. You can easily add all contacts to a group, and then share to all the numbers in the group just by typing the group name on the iSMS setting view.
How to initiate an iSMS session with contact groups.
- Create or import your contacts from the Contacts link at the top-right of your Magpi screen. Find instructions on how to import contacts from Excel here.
- Ensure that all contacts are assigned the same group
- On the iSMS sharing screen, share with the contact group
- All contact numbers will be listed in the iSMS sharing screen.
