I recently ported over to Optus. I can send sms and group sms (mass text) to a small number of people. I have tried sending to 34 recipients and it is failing, saying:
Message not sent: service not activated on network.
Is there a limit on the number of recipients?
Solved! Solved: Go to Solution.
Welcome to Optus and Yes Crowd.
Group SMS is for up to 20 recipients.
