Choose your data plan
Which plan type is right for you?

Fixed data plans give you a set amount of data, for example 1 GB or 5 GB, to use at full speed for the whole plan period. When it runs out, you top up or buy again. Pick this if you know roughly how much you'll use.

Unlimited plans never run out during the plan period, but each day includes a high-speed allowance. Once you use that day's allowance, you stay connected at a reduced speed until it resets 24 hours after you activate the eSIM. Pick this for heavier or less predictable use. A fair-use policy applies.
