# What does Not_Supported_Facility (Support Unavailable or Roaming Unsupported) mean?

The send is **not supported** in this case - for example the facility or feature is unavailable, or the recipient is roaming and the route does not support roaming delivery. The message was not delivered.

**What you can do:** Retry when the recipient is in a supported region or when the facility is available. If it persists, contact support.
