Mobile services in 4069 (Pullenvale) down since 3.30 pm. Tested on 2 separate phones and restarted them. Get an error of "Not registered on network"

My 2 Belong mobile data devices have no data this morning. My Boost phone (also on Telstra) and Telstra ADSL are working fine.

2 phones in the same household down for at least 48 hours. Cannot receive nor make calls - text and internet only available
