Which eSIM should I choose for the UK and mainland Europe?
For a UK-only trip, compare the plans here. If you are also visiting mainland Europe, compare the Europe plan and check that every stop is on its current country list.
Visiting more than one European country?
Compare the Europe eSIM and check every stop on your itinerary against its current country list. A regional plan can be a useful alternative to separate country plans.

What happens if I run out of data?
Top-up available. Unsure? Start small — you can top up along the way.
Can I keep my normal number?
Yes, in many cases you can keep your regular number on your primary SIM while using the eSIM for data. This gives you a flexible setup where you can still receive messages and use your normal number, while avoiding expensive roaming charges.
Yes. Select MondoMate for mobile data and enable data roaming on that eSIM at your destination. Disable data roaming and automatic data switching on your regular SIM to avoid unintended usage.
Does eSIM work on my phone?
Most newer smartphones support eSIM, but it depends on the model, manufacturer and whether the phone is carrier-unlocked. It's a good idea to check if your device is eSIM-compatible before purchasing, so you avoid surprises and can be sure everything works as expected.
