Travelling overseas

If you're travelling overseas, you can take your mobile handset, tablet or mobile broadband device with you and still enjoy great rates and coverage.

International roaming

If you are about to travel overseas and want to check if your mobile handset is unlocked to the Telstra network, ask a friend that isn’t on the Telstra network to borrow their SIM to insert into your mobile handset. This will provide a way to see if your mobile handset is unlocked from our network.

If the SIM works and your mobile handset receives mobile coverage, then your mobile handset is unlocked. However, not all mobile handsets are compatible with overseas networks, even if your mobile handset is unlocked.
