Call Disconnected in Mobile App Only

This issue could be caused by a weak or unstable internet connection, which interrupts the call. Another possibility is that the mobile app may have a software bug that affects its performance. Additionally, insufficient device memory or background processes could lead to the app crashing during a call.

If calling works for desktop dialer here, but it failed using the mobile app only:


Check if the Twilio Account SID is a master account.

  1. Once you are in the agency view, Click on "Settings"

  1. Depending on which location you are having this issue, make sure the account SID is different from the master Account SID on top.

  1. We always need to use a Twilio account SID to configure for the locations to call properly using the mobile app.

  1. Another common case is that the location user would provide their own Twilio SID, which might be a Master Account SID that won't work with the mobile app.

  1. If the move number tool is showing an error, please reach out to Twilio support to help move the numbers.
