When a global eSIM makes sense
A global eSIM makes sense for trips that cover several countries or include a stopover. You use one plan across your whole route, so you do not need to swap plans at each border.
Before you buy, check the country list. Each seller lists the countries its data covers. Make sure every place you visit is on it, including your stopover. Check each country by name, not just the region it belongs to. A missing country means buying a second plan just for that stop.
Only visiting one region? Compare Europe eSIM plans or USA eSIM plans. Or browse all travel eSIM plans in our tables.
How to compare global plans
Compare global eSIMs on price per GB first. It shows what each gigabyte costs, so different plan sizes are easy to compare.
Then check two more things. First, the number of days the plan lasts. Second, the country count each seller lists. A long list may still miss your route, so check each country.
A regional plan covers fewer countries, so it can cost less for that region. If you only visit Europe, compare eSIM for Europe too.
Our tables sort plans by price, cheapest first. When two cost the same, the plan with more data comes first, then the one that lasts longer. Each price is read from the provider's own website, with the date it was last checked.
Set it up once for the whole trip
Install your global eSIM at home on Wi-Fi, then switch to it when you land. You only set it up once for the whole trip.
Follow these four steps:
- Check your phone supports eSIM and is unlocked.
- Scan the QR code or tap install in the seller's app.
- On arrival, set the travel eSIM as your mobile data line.
- Turn off data roaming on your UK SIM.
Your plan's days usually start when it first connects to a network abroad. Keep your UK SIM on for calls and texts. Apps like WhatsApp and FaceTime still work on the eSIM's data.
Straight answers
Questions people ask
- What is the best global eSIM?
- Our table ranks global eSIMs by price, so the plan at the top is the cheapest. If two cost the same, the one with more data ranks higher, then the longer validity. Before you buy, check the country list and make sure your phone supports eSIM and is unlocked.
- Is a global eSIM more expensive than a regional one?
- It depends on the plan, so compare prices in our tables. Each travel eSIM table ranks plans by price, cheapest first, so the gap is easy to see. Every price is read from the provider's own website, and each table shows the date it was last checked.
- Does a global eSIM cover every country?
- Coverage depends on each plan, so check its country list before you buy. Make sure every country on your trip appears on that list. Then you can compare prices with confidence, because each table shows the date its prices were last checked.
- Can I use a travel eSIM on a locked phone?
- No, your phone must be unlocked to use a travel eSIM. Check your phone's settings, or ask your UK network whether it is unlocked. Your phone must also support eSIM, so check that before you buy.
- Can a travel eSIM receive texts?
- Most travel eSIMs are data only, so they cannot receive texts on their own number. Keep your UK SIM switched on and texts still reach that number as normal. Internet messaging apps like WhatsApp work over the eSIM's data, so you can message people that way.
- Can I use a travel eSIM as a hotspot?
- Some sellers limit hotspot use on some plans, so check the plan page before you buy. If you plan to share your connection, confirm that the plan allows it. This takes less than a minute and avoids a surprise at your destination.
