Can I change my phone number during the free trial?

Yes, if you would like to replace the free phone number associated with your trial account, you can by following these steps:

  1. Release your current number.
  2. Once you have released your current number, you can get a new number through the account signup interface, or you can use the phone number purchase interface.

Please note that you will not be billed for any numbers “purchased” durring your free trial. The billing cycle for phone numbers and billing for usage will only begin once you upgrade your account. All Twilio services you used prior to the moment you upgrade are free.
