ZenSim does not provide a truly unlimited highโspeed data eSIM for SouthโฏEastโฏAsia. All of the plans listed for the region have a defined data allowance, such as 3โฏGB per day for the โAsia+ Unlimited STANDARDโ bundles or fixed totals of 20โฏGB, 10โฏGB, and 5โฏGB for the other offerings. Fixedโdata plans can be more economical unless a traveler requires continuous highโspeed data beyond the capped amount, in which case a plan with a larger data supply might be chosen. For example, the Asia+โฏ20GBโฏโโฏ10โฏdays plan is priced atโฏ$32.00โฏUSD and lasts 10โฏdays, while the Asia+โฏ10GBโฏโโฏ30โฏdays plan costsโฏ$29.00โฏUSD and is valid for 30โฏdays.
