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.

Can I send SMS messages to roaming phone numbers?

Twilio cannot guarantee the deliverability of SMS messaging to roaming phone numbers.

If you decide to send an SMS message to a phone number roaming in an area other than where it normally operates, the SMS message may not arrive. In some cases duplicate messages may be delivered.

Twilio does not have the ability to determine whether or not the phone number you are sending SMS messages to is roaming at the time and SMS request is initiated.
