A United Kingdom eSIM costs from $1.94 (3GB for 15 days) to $10.03 (20GB for 30 days) and runs on 3, O2 and T-Mobile UK with 5G. There's also an unlimited plan at $1.94 a day, for 3 to 90 days. Validity starts on your first connection in United Kingdom, not on the day you buy, and your home number stays active for WhatsApp. You can share data over hotspot. Plans are data only; calls go through WhatsApp or other apps.
The UK has dense cellular coverage across nearly the entire urban area, so the real challenge usually isn't network quality — it's price. That's exactly where a local eSIM plan beats international roaming.

What should I know before a trip to United Kingdom?
In the UK the plan runs on O2 and T-Mobile UK on 5G, and on 3 on 4G. Note that the UK doesn't appear in the Europe plan's network list, so if your route also takes in Paris or Amsterdam, you'll need a separate plan for each side.
Before you fly: since January 2025 Israeli citizens need an Electronic Travel Authorisation (ETA) to enter the UK, applied for through the official UK ETA app or on gov.uk. In London itself you can pay for the Tube and buses directly with a contactless card or phone, without buying a separate travel card.
Frequently Asked Questions

Which networks does the UK eSIM use?
O2 and T-Mobile UK (part of EE) with 5G, and 3 with 4G. Your phone connects to whichever is strongest.
Does the UK eSIM work in Scotland, Wales and Northern Ireland?
Yes. The plan covers the whole United Kingdom.
Can I continue to Paris or Amsterdam on the same plan?
Not on this plan, which covers the UK only. The Europe plan covers the UK together with France, the Netherlands and 32 more countries.
Do I need an ETA to visit the UK?
Most visitors who don't need a visa, including Israeli citizens, need an Electronic Travel Authorisation (ETA) before the flight. You apply on gov.uk or in the official UK ETA app.
Are eSIM, digital SIM, and virtual SIM all the same thing?
Yes. An eSIM (also called a digital SIM or virtual SIM) is a SIM with no physical component, installed on your device by scanning a QR code instead of inserting a card. You use it exactly like a regular SIM for data abroad, without hunting for a SIM kiosk at your destination.
Does my device support eSIM technology?
Most smartphones released in the last five years support eSIM. We recommend checking your device settings, or looking up your phone model in the FlySim compatibility checker. Open the compatibility checker
How exactly does activation work?
After payment, you'll receive a unique QR code by email. Scan it in your device's cellular settings (Add eSIM), confirm, and that's it.
