We never expect a loss of service when you port your numbers to Twilio. To ensure this seamless experience, there are two things that you should do:
- Continue your current service with your carrier, PBX, app, etc. for at least 10 days past the scheduled port date. For instance, you should continue to pay for existing phone service with your current carrier until you’ve verified that calls are routing to Twilio as expected. This way, if the scheduled porting time is delayed for any reason, you can ensure that your current coverage will continue.
- Make sure to fully test and configure your Twilio app at least 48-hours before your scheduled port date. Since port times occasionally vary, it’s imperative that you have your app up and running when the number re-routes to Twilio. If your app is not running and properly configured, your phone service won’t work as expected after the port occurs, even though traffic has been re-routed to Twilio.
