Dear Customers,

The carrier mentioned above has informed us of maintenance on their SMS platform.

There is no expected customer impact as a result of this maintenance; however, in the unlikely event of a disruption to the service, MO/MT SMS will be queued on the Opeperator's SMS gateway for delivery once the maintenance has been completed.

If you have any questions, please contact us at

Kind Regards,
TeleSign Support
