The Moroccan Networks currently require all sender IDs to be replaced with a fixed sender, we will generally use 'NXSMS'.
We recommend you register your sender ID with us to avoid filtering and forcing, this can be done through your account manager. Unregistered sender IDs will likely be changed to 'Info'.
There are no additional content restrictions beyond those in our Acceptable Use Policy
Other features/restrictions of note:
Handset delivery receipts are supported.
