To begin the process of porting away from Twilio, you need to follow a few simple steps to get the information that you need to port. This is known as CSR information.
1) Reach out to Twilio porting support (email@example.com) to request a copy of the CSR information for the numbers on your account that you wish to port away.
This may take Twilio sometime as they need to reach out to their underlying partners to confirm this information with each of them.
2) Once you receive the CSR information from Twilio, you can now proceed with submitting your port-in request to Telnyx. To do this, please see Porting into Telnyx.
If you are porting a large amount of numbers into Telnyx, when filling out the LOA, please state "Numbers provided in spreadsheet" in the "Numbers to be ported" field.
Please put your own company information on the LOA. This should include your own business name, address, Authorized person's name and signature as well as the date.
Twilio does not leverage BTNs (billing telephone numbers) or Account numbers. You can use any of the numbers that you are porting away from Twilio as the BTN and as the Account Number too.
