Sending SMS to Maroc Telecom (IAM) — what you need to know

Maroc Telecom (IAM) is the historic operator and the largest in terms of subscriber share in Morocco. EnvoiSMS.ma has a direct connection to its SMSCs.

Common IAM number ranges

+212 661, 662, 666, 667, 668, 670–673, 676–678, 700 (indicative list, subject to change depending on ANRT allocation)

Points of attention

• IAM applies strict Sender ID filtering: an unregistered name may be blocked or substituted
• Very high volume campaigns sent at a peak can be temporarily regulated by the operator — EnvoiSMS.ma automatically smoothes sending to stay below the throttling thresholds
• IAM acknowledgments (DLR) are typically received within seconds

In the event of non-delivery to IAM

First check that the number is active (not canceled) and that the Sender ID used is validated for this operator, before opening a support ticket.
