Follow these steps to successfully port your number to Twilio (and use it with Telfon):

1. Submit a Porting Request
   
   
   • Log in to your Twilio Console 
     
     
   • Click on Phone Numbers > Port & Host > Port in request
     
     
2. Keep Your Current Provider Account Active
   
   
   • Do not cancel your existing service until the port is complete.
     
     
3. Twilio’s Carrier Partner Will Contact Your Current Provider
   
   
   • They will handle the process of transferring your number.
     
     
4. Wait for Approval or Rejection
   
   
   • You’ll receive a notification.
     
     
   • Common reasons for rejection: incorrect account details or an unauthorized Letter of Authorization (LOA).
     
     
5. Pre-Configure Your Number in Twilio
   
   
   • Once approved, log in to your Twilio Console and configure routing settings before the porting date.
     
     
6. Complete the Port and Disconnect from Your Old Provider
   
   
   • After the port is successful, you can safely remove the number from your old service provider.
