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.

  1. 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.
  2. Ensure that all contacts are assigned the same group
  3. On the iSMS sharing screen, share with the contact group 
  4. All contact numbers will be listed in the iSMS sharing screen.
