Optus sells roaming in two families. International Roaming (prepaid) is bought by prepaid customers for Zone 1 destinations. It comes in four validity periods: 1 day with 1GB, 14 days with 5GB, 28 days with 10GB and 186 days with 15GB. The Optus Roaming Pass (postpaid) is the postpaid option, charged per day of use, and gives 1GB of data plus unlimited standard calls and texts for each 24 hours of use in Zone 1 destinations. Optus Zone 1 covers 24 popular destinations, so the destination list decides whether either family applies to a given trip.
The two families are charged differently. The International Roaming (prepaid) packs are bought for a set validity period, so the 1 day, 14 day, 28 day and 186 day options are each a single purchase covering that window. The Optus Roaming Pass (postpaid) is charged per day of use on eligible postpaid plans, so the charge follows the days the pass is actually used rather than a fixed block. Each day of the pass includes 1GB of data with unlimited standard calls and texts.
A traveller can keep the Optus SIM in the phone for calls, texts and bank codes and add a data-only travel eSIM for mobile data. The eSIM connects to local networks with automatic network selection, and it is installed by QR code before the trip and switched on when the traveller lands. A data-only eSIM has no phone number, so calls and texts stay on the home SIM or go over internet apps. This arrangement suits a trip where the destination is outside the 24 Zone 1 countries, or where the Optus pack size does not match the length of stay. The table above lists each Optus pack with its live price beside live data eSIM prices for the same trip, destination by destination, so the destinations where the eSIM costs less are visible there. For a closer comparison of the two approaches, see eSIM vs roaming compared, and for trips leaving Australia see roaming from Australia.
Slashtel sells prepaid data-only travel eSIMs for 190+ countries.
