Whether you’re landing at Heathrow, taking the train up to Edinburgh, or exploring the Welsh coast, a travel eSIM keeps you online across the UK without roaming charges or a trip to a phone shop.
Why use an eSIM in the UK?
An eSIM is a digital SIM already inside your phone. Buy a UK data plan online, scan one QR code, and connect to a local network automatically.
- No roaming bills — a common nasty surprise for visitors using a home carrier.
- Online instantly the moment you land.
- Keep your number for calls and texts; the eSIM handles data.
Will my phone work?
Phones from 2019 onward almost always support eSIM (iPhone XS+, recent Pixel, Galaxy S20+), and must be carrier-unlocked.

How much data do you need in the UK?
- Light (maps, messaging, browsing): a small daily allowance.
- Average tourist (maps, social, photos, transport apps): a mid-size plan.
- Heavy / business / remote worker (streaming, video calls, tethering): a large or unlimited-style plan.
4G/5G coverage is excellent across UK cities and towns, with the usual thinning in remote Highlands and rural areas. See current UK plans and prices. Plans start from just $0.70.
