How much does a United Kingdom eSIM cost?
A United Kingdom travel eSIM from roamsync.co starts at $0.66 for 102 MB valid 7 days. 42 plans are available for United Kingdom, priced from $0.66 to $63.95, with validity from 1 day to 180 days. Data allowances run from 102 MB up to 100 GB. 6 unlimited-data options are also offered, subject to a fair-use policy. Connections run at 5G / 4G / 3G / 2G speeds on local partner networks. Every plan is data-only: it carries mobile internet but does not include a local United Kingdom phone number, so calls and messages travel over internet apps such as WhatsApp. Activation is by QR code, delivered to your email and WhatsApp within seconds of purchase, and the profile installs in about two minutes on any eSIM-capable iPhone, Samsung or Google Pixel. The most popular United Kingdom plan is 102 MB for 7 days at $0.66. Plans can be bought and installed before departure, so the eSIM is ready the moment you land.

United Kingdom eSIM FAQs
Answers to the questions we get asked most often.
Pricing and coverage details last updated
Yes. 4G is available at most central London Underground stations following TfL's station connectivity rollout.
Yes. Our UK plans provide nationwide coverage including Scotland (Edinburgh, Glasgow, Highlands), Wales, and Northern Ireland.
Yes. We offer extended-duration plans (30 days and above) suitable for semester-length stays.
Most eSIM-capable phones from the last few years work fine — this includes iPhone XS and later, Google Pixel 4 and later, Samsung Galaxy S20 and later (including Z Fold/Flip models), and recent OnePlus and Motorola devices. Your phone also needs to be carrier-unlocked. If you're not sure, check our device compatibility checker before you order.
While you're still on Wi-Fi (ideally before you fly), open Settings on your phone, go to Mobile/Cellular Data, choose Add eSIM or Add Data Plan, and scan the QR code from your order confirmation. Leave the new eSIM line installed but inactive until you land, then switch on Data Roaming for that line.
Yes. The eSIM runs on a separate line purely for data, so your existing SIM stays in the other slot for calls and SMS on your normal number — most travellers keep both active throughout their trip.
Yes — once the data line is active, every internet-based app works exactly as it would on a local SIM: WhatsApp, FaceTime, Google Maps, ride-hailing apps, streaming and email all run over the eSIM's data connection with no extra setup required.
You won't be cut off with unexpected charges — instead, simply come back to roamsync.co and purchase another plan or a top-up (where supported, this is shown as the plan's Top-Up Protocol in the order details). The new data is applied to the same eSIM profile, so there's no need to reinstall anything.
