Unlimited eSIM: daily high-speed allowance by country

Every “unlimited” travel eSIM has a daily high-speed allowance. The local network sets the tiers that exist, and every provider decides which tier it buys — including us. Once you pass the daily amount, data keeps working at a reduced speed for the rest of that day and returns to full speed the next day. Nothing is cut off, and hotspot traffic counts towards the same allowance.

This is the question travellers ask most often, and almost nobody answers it with numbers. So here is the tier we actually buy, for each of the 181 countries where we sell unlimited plans.

This is how the whole industry works

The mechanism is not specific to us. Airalo’s own help centre states that unlimited packages may include a fair usage policy which reduces connection speed after a set amount of data in one day, gives 3 GB as its example, and notes that the reduced speed applies only until the next day. Holafly’s terms and conditions state that speed may be subject to the network provider’s fair use policy. What differs between providers is not whether the limit exists — it is whether the numbers are published.

If you need full speed for the whole trip

Then an unlimited plan is the wrong product, ours included. Take a fixed data package instead: 3–50 GB for 191 destinations, full speed until the data is used up.
