eSIM.sm does not provide an unlimited data eSIM for Australia. All available plans have a fixed data cap, ranging from 3GB to 50GB over varying validity periods. Travelers who need more data can choose from the highโcap options, such as the 50GB 60โday plan or the 20GB 30โday plan, both of which include tethering. These fixedโdata plans can be more costโeffective for moderate to heavy data use, but a user who expects to consume more than the largest cap would need to consider buying a second plan or looking for an alternative provider that offers truly unlimited data.
