🇬🇧 United Kingdom
London eSIM
Land in London, scan a QR, and you're online on a local network in seconds. No daily roaming fee, no surprise bill. $0.90 per GB.
Data in London
In London the eSIM rides EE and O2 and Vodafone with 5G typically available - the same towers local subscribers use, selected automatically by signal strength. City centers, transit, and airports are the strongest coverage any network offers, so this is the easy case. Near-universal in cities and towns. The Scottish Highlands and rural Wales drop to 4G or 3G in places, as they do for domestic SIMs.
Pricing is United Kingdom's flat rate of $0.90/GB, metered per MB from a prepaid USD balance. A city break runs light: maps, ride-hailing, translation, and messaging together use well under 500 MB a day for most travelers, so $10 (≈ 11.1 GB) commonly outlasts the trip - and whatever's left keeps working in the next city, or next year.
Arrival checklist
- 1. Install the eSIM on Wi-Fi before you fly (QR or one-tap iPhone install).
- 2. Turn Data Roaming ON for the Anon eSIM line; leave it off on your home SIM.
- 3. Set Anon eSIM as the mobile data line; keep calls/SMS on your primary.
- 4. Land in London, drop airplane mode, and you're connected within a minute.
No ID, no account, no email - $5 minimum plus a one-time $5 setup fee for a new eSIM. Top-ups later are fee-free.
On the ground in London
Heathrow, Gatwick, and Stansted are fully covered gate-to-gate on EE and Vodafone; the Anon eSIM attaches during taxi. Central London runs 5G on EE (typically 150-350 Mbps) with strong LTE fallback everywhere else. The Elizabeth line, most of the Jubilee line, and the newest Tube segments have continuous underground coverage; older lines are patchy but improving. Buses and Overground work throughout. If you're going out to the Cotswolds or Cornwall, LTE holds up but 5G thins out - fine for maps and messaging, less so for video calls.
