Phone Number Does Not Have Correct Messaging Service Capabilities

In order for a phone number to work in a Messaging Service it must have at least SMS or MMS capabilities. If it does not have either, it will fail.

Possible Causes

  • The phone number you are trying to add to the Messaging Service does not have SMS or MMS capabilities.

Possible Solutions

  • The Active Numbers page in the Twilio Console will display the capabilities of each of the phone numbers in your account.
  • Find a new phone number that has SMS and/or MMS capabilities depending on your use case and business needs, and add that phone number to your Messaging Service.
