I deleted an sms connection for tenant and all users related to this connection also were deleted. Is there a some way to restore connection and users or at least users?
Unfortunately, it looks like this is an Unsupported request according to the docs.
Restore any deleted or modified data or settings in tenants, including
- Database connections and their users and passwords
- Users, their profile information, metadata, and role memberships
More info can be found in this FAQ link as well Backup / Restore Policy for Public Cloud Tenants
