21408: Your account is not allowed to send SMS to this country or region

You have attempted to send an SMS or MMS to a region that has not been enabled in your account. These settings exist to help you ensure you only send SMS or MMS to the countries or regions you operate in, and avoid unexpected charges.

Possible Causes:

Possible Solution:

  • If you wish to send messages to this region, please contact Support.

21614: 'To' number is not a valid mobile number

You have attempted to send an SMS with a 'To' number that is not a valid mobile number. It is likely that the number that you have specified is a landline number or is an invalid number.

Possible Causes:

  • The number you provided may be a landline number.
  • The number you provided may be invalid or formatted incorrectly.
  • If you are attempting to send SMS to Internet of Things (IoT) or machine-to-machine (M2M) numbers, the numbers may use a non-standard format that the CRM has not added to its number validation system yet.

Possible Solutions:

  • Confirm that the number you are sending to is not a landline.
  • Please verify you have provided a valid mobile number in proper E.164 format.
  • If you are attempting to send SMS to an IoT or M2M number, check whether the number format is different from the standard mobile numbers in that country or locality.
  • If you believe this is the issue, please contact Support for assistance.
