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.
The connectivity and bandwidth requirements for Twilio's Javascript, iOS, and Android SDKs can vary depending on the version in use. For a complete rundown of the connectivity needs for each SDK, see Voice SDKs Network Connectivity Requirements.
