If a Toll-Free number is the only number assigned to a user, SMS will not function for that user. Toll-Free phone numbers are prohibited from sending/receiving SMS messages.


For SMS capability, a local phone number must be assigned to a user profile in 8x8 Admin Console. If there is no local phone number assigned to a user attempting to use SMS, you must first assign them one and Save their user profile.

Users must log out of 8x8 Work and log back in for any Admin Console changes to take effect.
