What an eSIM is and why travellers use one
An eSIM is a digital SIM built into a phone. It works without a plastic card, so there is no need to open a tray or find a shop after landing. A travel eSIM adds a local or regional data plan alongside the home SIM, which means the phone can keep its usual number for calls and messages while data comes from the travel plan. Travellers use eSIMs because they can set one up before a trip and have data ready on arrival. The phone must be unlocked and eSIM compatible. Plans are data only, with no voice calls or phone number.

How buying works
Buying an eSIM from Slashtel is done online. The QR code is delivered instantly by email. The plan starts when it first connects, so it can be installed before travel and will not begin until the phone reaches the destination. Customers can buy as a guest or create an account with a one-time email code, which means no password is needed. An account lets users view their eSIMs, check live status and data usage, and add data. Support is available on WhatsApp.
Who it suits
The service is aimed at several groups. International students arriving for the September intake can install a UK eSIM before they fly and have data ready when they land. UK travellers going abroad can use a travel eSIM for another country instead of relying on their home plan. Families topping up a relative's UK mobile can use the recharge service, which is priced in pounds. The Arrival Bundle is designed for people landing in the UK who need a short term data plan and a longer 30 day plan.
Things to check first
Before buying, check that the phone is unlocked and eSIM compatible. A locked phone will not accept a travel eSIM, and not all models support eSIM. The plans are data only, with no voice calls or phone number, so calls and texts must come from another SIM or app. The eSIM QR code is sent by email, so a stable email address is needed. The plan starts when it first connects, which allows installation before travel. Prices are in US dollars for eSIMs and in pounds for UK mobile recharges.
