A2P 10DLC Campaign Vetting Delays: Twilio cannot approve 10DLC Campaigns ourselves, and must rely on third parties who control our connections to carriers to sign off. These external processes are creating several week delays for our customers. We continue to escalate these issues and are working to reduce delays wherever possible. Further details will be shared in the Campaign Vetting Changes article as they become available.

Which carrier networks are supported by Twilio SMS?

Twilio SMS supports global carrier networks with coverage in 150+ countries. For information about what networks and countries are supported, please visit our coverage & pricing page.

If a carrier is not listed then Twilio does not currently support that carrier at this time. If your application attempts to send an SMS message to a carrier which we do not support, Twilio API will respond with an error to the request. You will not be charged for this attempt.

Twilio is constantly expanding our global coverage by adding new carriers. Please write Twilio support and let us know which carrier network you'd like to reach.
