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.

Belgium Porting Process 

  1. Submit your porting request with all the requirements in place to porting@twilio.com. 
  2. Twilio approves the port request. If everything in Step 1 is correct, you can expect Twilio to approve your port request within 24 business hours.
  3. Twilio submits the number to the Carrier Partner. This can take up to 24 business hours. Your request is then submitted to your soon-to-be former carrier as a port request. During this time, do not close your account with your carrier and keep your numbers active.
  4. Twilio’s Carrier Partner reaches out to the Losing Carrier. This can take around one week to complete.
  5. Response from the carrier. At this point, your request is either approved or rejected:
    • Approved: If approved, Twilio will notify you about a porting date. 
    • Rejected: Rejections can occur due to various reasons. For example, invalid VAT Number or invalid/incomplete range of numbers. Read more about common reasons for port request rejections here. Additionally, you will likely need to reach out to your losing carrier to find out what’s needed to move forward. Rejections may add an undetermined amount of time to your porting request.
  6. Twilio reaches out to you with a porting date. Twilio emails you with a porting date and time slot if known. Your number is on your Account and can be visible in the Twilio Console.
  7. Configure your number. It is critical to configure your number prior to the porting date. This will minimize the service downtime. You can configure the numbers from the Twilio Console.
  8. Your phone number is with Twilio. Once your number(s) is routing to Twilio and everything works as expected, you can remove the number(s) from your former provider.

We charge a one-time porting fee for Belgium, for more details please reach out to porting@twilio.com.
