Investigating

We have received reports from callers encountering a 'congested' message or busy tones when dialling certain Simtex numbers using Telstra mobile services. It's important to note that this issue appears to affect only a specific subset of Simtex number ranges.

The root cause of the problem lies with an upstream carrier interconnect fault, preventing these calls from reaching the Simtex voice network. Unfortunately, we currently do not have an estimated time for restoration.

Our next update on this issue is scheduled for 12:00 PM AWST.

Thank you for your patience.
