One news.com.au reader suggested that if you change your settings to GSM or 2G only, that will allow you to call again, but will limit your data speeds.

Optus users are also reportedly experiencing issues, with many taking to social media to report that their numbers have ‘been blocked’ from the network. Other mobile providers like Virgin and Amaysim which use Optus’ networks have users who are also reporting problems.
