    Service Restrictions

    • Toll-free (800) numbers are not reachable from countries other than Austria. 
    • Reachability issues have been reported when dialing the 720 range from several carriers outside of Austria, therefore, international reachability cannot be guaranteed.
    • Inbound SMS to an Austrian number is not supported.
    • Outbound SMS from an Austrian number is supported to Austrian SMS-capable numbers only.
