Due to restrictions from the local network, all A2P (application to person) traffic to CubaCel (36801) must have the Sender ID whitelisted before the traffic will be accepted. If your Sender ID has not been whitelisted by Nexmo then your SMS will be rejected up front and you will not be charged for the SMS. It is only possible to whitelist alpha Sender IDs.

To register your use case or whitelist your Sender ID, please contact and we can begin this process.
