Simtex has implemented a system which blocks access to certain international country codes by default.

This ensures higher-risk destinations cannot be called without our staff giving access to higher tiers.

By default, each Simtex account has IDD disabled, you will need to request to have this activated by contacting support@simtex.com.au
Let our staff know which IDD tier you would like to have access to.
