Who needs unlimited data abroad
Heavy users need unlimited data abroad: streamers, laptop workers and people on long trips. Most short trips need far less. A city break usually needs a much smaller plan.
Streaming video uses far more data than messaging or browsing. Films and live sport can use up a plan quickly. A hotspot shares your phone's data with a laptop or tablet, so laptop work uses more too.
Long trips add up, even with light use. Check your normal monthly data in your phone's settings first. Then compare eSIMs for Europe or eSIMs for the USA. Our tables rank plans cheapest first, so start at the top.
What unlimited can still limit
Sellers may slow your speed after a daily amount of data, or limit hotspot use. So the word "unlimited" alone does not tell you the whole story. Two plans with the same label can work very differently.
Read the seller's plan page before you buy. Look for three things. The daily amount, the speed after it, and any hotspot rules. If you plan to stream or work on a laptop abroad, check these closely.
Every price in our tables is read from the provider's own website, and each table shows the date we last checked it. Once you know the limits, compare eSIMs for Europe or eSIMs for the USA.
How to pick one
Compare the price per day, not the headline price. Divide the total cost by your trip length, so short and long plans compare fairly.
Check the region next. A plan for Europe may not cover the USA, so confirm the countries on the seller's site. See our Europe eSIM plans or USA eSIM plans.
Pick a data-only plan. It gives you internet but no phone number, so keep your UK SIM on for calls and texts. WhatsApp, FaceTime and other internet calling apps still work.

Straight answers
Questions people ask
- Is an unlimited data eSIM really unlimited?
- Not always. Sellers may slow your speed after a daily amount of data, or limit hotspot use. Read the seller's plan page before you buy, so you know exactly what you get.
- Can I use an unlimited eSIM as a hotspot?
- Check the seller's plan page first, because hotspot use depends on the plan. A hotspot means sharing your phone's data with a laptop or tablet. Look for hotspot use in the plan details before you buy, especially if you work on a laptop abroad. If the page does not mention it, do not assume it is included.
- Which is the cheapest unlimited eSIM for Europe?
- The cheapest unlimited eSIM for Europe is the first unlimited plan in our Europe table, because tables rank plans cheapest first. Scan down from the top of the eSIMs for Europe table to find it. If two plans cost the same, more data ranks first, then longer validity, and each table shows the date its prices were last checked.
