What is the best eSIM for the UK?
+
eSIMbundle is a strong choice if you want British mobile data on the phone you already own: one eSIMbundle eSIM, a UK data bundle before departure, and a VPN included. Land at Heathrow, Gatwick, Stansted, Manchester or Edinburgh already on Google Maps, Citymapper, National Rail, TfL Go, Uber and WhatsApp — no British SIM required.
Which mobile network does eSIMbundle use in the UK?
+
Your eSIMbundle eSIM connects automatically to an available British partner network when you land, so there is no carrier to pick at the airport. The UK is served by a small number of national operators; which one you end up on can vary by location and time.
Does eSIMbundle have good coverage across the UK?
+
Coverage is generally strong across British cities and along the main National Rail corridors. Signal can weaken inside long Tube tunnels between certain stations, on rural rail routes through open countryside, in parts of the Scottish Highlands and in some remote coastal areas.
Is 5G available with a UK eSIM, and how fast is it?
+
4G is broadly available in populated UK and 5G is generally strong across London and other major city centres. Whether your phone connects on 4G or 5G depends on your device, location, available partner network and live conditions — speeds are typically comfortable for navigation, video calls, streaming and moderate hotspot use.
How much data do I need for 7, 15 or 30 days in the UK?
+
Light users on Maps and messaging often manage on 1–3 GB a week. Normal travellers using Citymapper, National Rail, social media, streaming and hotel bookings usually want 5–10 GB a week. Heavy video or hotspot use can push past 20 GB a week. Use the Travel Data Calculator to size a UK plan for your trip.
Does a UK eSIM include a British phone number, calls or SMS?
+
eSIMbundle UK plans are data plans. Use mobile data for WhatsApp, iMessage, FaceTime and other internet-based calling and messaging. Keep your normal SIM active for calls, SMS and verification messages, subject to your home carrier's roaming charges and support.
Can I keep my normal SIM, phone number and WhatsApp?
+
Yes. On a compatible dual-SIM phone, keep your normal SIM installed and use your eSIMbundle eSIM for mobile data. Your normal number stays with your home SIM, and WhatsApp and iMessage continue using the numbers already registered to your accounts.
Can I add more data while I am in the UK?
+
Yes. Sign in to your eSIMbundle account and add another UK data bundle whenever you need more. The new bundle activates on the same eSIM already installed on your phone — no new QR code, no reinstall.
Should I buy my UK eSIM before travelling?
+
Yes. Buy your bundle and install the eSIMbundle eSIM before departure while you have a stable internet connection. Then arrive in the UK, turn off airplane mode and you're online — no phone-shop detour and no roaming charges.
Does eSIMbundle include a VPN in the UK?
+
Yes. A VPN is included with every eSIMbundle plan at no extra cost. Switch it on in the app for a more private connection on British mobile data and on airport, hotel and café Wi-Fi.
Can I use the same eSIM elsewhere in Europe after the UK?
+
Yes. The eSIMbundle eSIM stays installed on your phone. When you travel next, add a bundle for another supported destination in your account and it activates on the same eSIM — no new installation required.
