All SMS sent with numeric Sender IDs to MTN Sudan (63402) and Zain (63401) will be blocked by the operator.
To overcome this:
- Any messages sent via Nexmo with numeric Sender IDs will be automatically changed to "SMS" or "NXSMS"
- Any messages sent via Nexmo with alphanumeric Sender IDs will remain unchanged and will deliver as normal.
There are no additional content restrictions beyond those in our Acceptable Use Policy
Other features/restrictions of note:
Handset delivery receipts are supported.
