Why use one
Roaming policies on UK networks vary, and daily roaming charges add up quickly on a week away. A travel eSIM gives you a fixed amount of data for a fixed price, bought before you go.
Check your phone first
Your phone must support eSIM and be unlocked. Most iPhones from the XS/XR onwards and many recent Android phones do. On iPhone, look under Settings → General → About for "Digital SIM" or "Available SIM".
How to set it up
- Buy a plan for your destination before you travel.
- Install it over Wi-Fi at home by scanning the QR code or following the in-app steps.
- Leave it switched off until you land, then turn it on and enable data roaming for the eSIM line only.
- Keep your main SIM on for calls and texts, or turn its data off to avoid charges.
Tips
- Pick a regional plan if you're visiting several countries.
- Hotspotting works with most plans, but check the plan details.
- Delete the eSIM once you're home and the plan has expired.
