How to choose
Pick the data, then the price
The data you need depends on how many days you are away and what you use your phone for. Maps, messages, social media and streaming can all change how much you need, so think about your own habits.
Start with how much data you use at home, then count the days you will be away. Choose a plan with a little spare, so you do not run out halfway through your trip. Before you buy, check the data amount and number of days in our table.
Your phone must support eSIM and be unlocked before you buy a travel eSIM. Unlocked means it is not tied to one network. iPhones from the iPhone XS and XR (2018) onward support eSIM. Recent Samsung Galaxy and Google Pixel phones do too. Then check your UK plan. Many UK plans charge a daily fee in Europe and further afield. Others include EU roaming. Check your own plan before you travel. If you pay a daily fee, compare SIM-only deals to find a better fit.
The cheapest travel eSIM is the one with the lowest price for the same data and days. Compare plans with the same data and number of days, then sort our table cheapest first. Pick a regional plan for one area, such as Europe, or a global eSIM if you visit several countries. Most travel eSIMs are data only, so keep your UK SIM switched on for calls and texts. Every table shows the date its prices were last checked, so you know how current they are.
Straight answers
Travel eSIM questions
- What is a travel eSIM?
- A travel eSIM is a SIM built into your phone that gives you mobile data abroad for a set number of days. You add it by scanning a QR code or tapping install in the seller's app, so nothing is posted to you. Most travel eSIMs are data only, so you keep your UK SIM on for calls and texts. Internet calling apps like WhatsApp and FaceTime still work over the data.
- Will a travel eSIM work on my phone?
- Yes, if your phone supports eSIM and is unlocked, meaning it is not tied to one network. iPhones from the iPhone XS and XR (2018) onward support eSIM, as do recent Samsung Galaxy and Google Pixel phones. Check this before you buy, so you do not pay for a plan your phone cannot use.
- Do I keep my UK number with a travel eSIM?
- Yes, your UK number stays on your UK SIM. Most travel eSIMs are data only and have no phone number of their own. Keep your UK SIM switched on for calls and texts, and use WhatsApp or FaceTime over the eSIM's data.
- When should I install my travel eSIM?
- Install your travel eSIM at home on Wi-Fi, before you leave for your trip. The plan's days usually start when it first connects to a network at your destination, so installing early does not waste your days. Once installed, you can switch it on when you land, then set it as your mobile data line.
