UK eSIM for Visitors to London, Edinburgh and Beyond, from $2.03

The best eSIM for the UK is one you install before you fly, that needs no app and that you can top up if you run low. The GleeSim UK eSIM is bought and managed on WhatsApp, so your QR code arrives in the chat in about 60 seconds and you can switch it on when you land. Most visitors choose a 5GB or 10GB plan for a trip of one to two weeks.

No. GleeSim has no app and no account to create. You order, get your QR code, check your data balance and top up inside one WhatsApp chat, and real people answer 24/7.

The plans are made for the whole of the UK. Signal is strong in cities, towns, airports and along main rail routes. Remote areas such as the Scottish Highlands, islands and some Welsh valleys can have weaker or patchy coverage on any network, so download offline maps before heading out.

Mobile coverage on the Tube is still being added in stages, so some stations and tunnels have signal and many sections do not. Plan on gaps between stations, and download your route or use Transport for London's station Wi-Fi for the deeper sections.

No. GleeSim UK plans are data only, so there is no +44 number for normal calls or SMS. You can still call and message over WhatsApp, FaceTime, iMessage and similar apps. Your own SIM stays in the phone, so your home number keeps working for calls and for any bank or login codes sent by SMS.

For a week of maps, messages, social media and some video calls, 5GB is usually enough. For two weeks or regular streaming and tethering, choose 10GB. 20GB suits a month, students and remote workers, and the 15 day Unlimited plan is for heavy use on a shorter trip. If you run out, we add more to the same eSIM on WhatsApp.

Yes. The eSIM works as a second, data-only line. Your own SIM stays in the phone, so your WhatsApp number, chats, groups and contacts do not change. You only use GleeSim for the data connection.

Install it at home or at the departure airport on Wi-Fi, before you fly, so you are not setting things up after a long flight. Each plan's validity is shown on its offer page. If you are unsure when the validity starts for your plan, ask us on WhatsApp before you travel.

Most phones from 2019 onward support eSIM, including recent iPhones, Samsung Galaxy S20 and newer, and Google Pixel 3 and newer. Your phone also needs to be unlocked from your home network. Not sure? Send us your phone model on WhatsApp and we will check.

It depends on your home network. Many providers charge a daily fee or per-MB rates for data in the UK, and the cost adds up over a week or two. A GleeSim eSIM is a fixed price paid once before you travel, so there is no bill when you get home. Check your own network's current UK rate to compare.

Message us on WhatsApp and we add more data to the same eSIM within minutes. You do not need a new QR code or a new profile.

Yes. Order on WhatsApp from anywhere and tell us how many phones you need. We send one QR code per phone, and we can talk them through the installation in the chat.
