We're a leading Australian travel business focused on bringing affordable telecommunication solutions for outbound Aussie travellers. Since our inception, we have helped over 150,000 Aussies connect like locals abroad and and save on having to pay roaming fees.

Are there any hidden fees?

All of our products are Prepaid. The features and allowances on each of our International Travel SIM and International eSIM are all disclosed upfront. So you know exactly what you're getting when you purchase and there are no hidden surprises later on.

Can I use my SIM on a cruise?

All of our Prepaid Travel SIMs work in areas where cellular signal is available. At open sea, when you're outside range of network towers, cellular signal may be weak or not available. However coverage will be available closer to port.

Can I keep my Australian number?

You can keep your Australian number active for calls & SMS while using a travel SIM or eSIM for data, If your phone supports dual SIMs (International roaming fees can apply). However, please note that having 2 SIMs enabled on roaming can cause conflicts where both SIM profiles compete on the same network for connection. For good practice, we always recommend turning off your Australian SIM unless you need it to receive important calls or texts.

SIM and device compatibility?

Your phone needs to be unlocked to be able to use our SIMs. If you're unsure whether if your phone is unlocked, please contact your telco provider to check. If your phone has been issued to you from your employer, please check with them for compatibility as some work devices have additional security applications installed. Some foreign networks have region specific frequency band requirements (eg USA). Which makes those networks less compatible with Australian phones. Please make sure you read the product information and use the network's own compatibility checkers where advised and applicable.
