eSIM FAQs

Common questions about using eSIM in United Kingdom

Which UK networks does Esimy connect to?

Esimy UK eSIM connects to all four major UK mobile networks: EE (BT-owned, the UK’s largest 5G operator), Vodafone UK, O2 (Telefónica UK), and Three UK (CK Hutchison). Your phone automatically picks the strongest available signal at your location — no manual carrier switching.

What you get on each:

  • EE: the UK’s most extensive 4G/5G network — strong in London, Birmingham, Manchester, and major cities; widely regarded as the UK leader for rural coverage
  • Vodafone UK: excellent urban + rail-corridor coverage, growing 5G footprint
  • O2: reliable UK-wide coverage including Northern Ireland, Wales, Scottish Highlands
  • Three UK: data-heavy 4G plans, extensive 5G in city centres

Coverage extends through England, Scotland, Wales, and Northern Ireland — including Edinburgh Castle, the Scottish Highlands, the Cotswolds, the Lake District, the Welsh coast, and remote rail routes. Plans from €1.99 / 1 GB / 7 days, hotspot included on every tier. 5% Loyalty Points back into your Esimy Wallet on every purchase.

How much does an eSIM for the UK cost?

Esimy UK single-country plans start at €1.99 for 1 GB / 7 days — the cheapest tier for short London city breaks. Full pricing ladder:

  • 1 GB / 7 days — €1.99
  • 3 GB / 30 days — €3.99
  • 5 GB / 30 days — €4.99
  • 10 GB / 30 days — €8.99
  • 20 GB / 30 days — €14.99

Hotspot/tethering, instant QR activation, and 4G/5G coverage on all four UK networks (EE, Vodafone UK, O2, Three UK) are included on every tier — no add-ons, no Brexit roaming surcharges, no surprise charges at month-end. Validity starts when you first activate (not at purchase), so you can buy weeks in advance without burning days.

Travelling through the UK plus mainland Europe? The Esimy Europe regional plan covers 47+ countries (including the UK) from €1.99 / 1 GB / 7 days, with €9.49 for 5 GB / 45 days as the sweet-spot multi-country tier. 5% Loyalty Points back as cashback into your Esimy Wallet — accumulates into a free top-up over time.

Does Brexit affect eSIM roaming between the UK and EU?

Yes — since Brexit, the UK is no longer part of the EU “Roam Like at Home” zone, which means most UK home mobile contracts now charge roaming fees in EU countries (and most EU contracts charge roaming in the UK). Typical roaming surcharges are £2–£8 per day depending on the carrier — and several UK operators capped or removed inclusive EU roaming entirely in 2022–2024.

An Esimy eSIM bypasses Brexit roaming completely. Two ways to use it depending on your trip pattern:

  • UK-only trip from EU: use the Esimy UK eSIM (€1.99 / 1 GB / 7 days up to €14.99 / 20 GB / 30 days) — connects to EE, Vodafone UK, O2, Three UK as a local-grade plan, no UK contract or address needed.
  • UK + EU trip combined: use the Esimy Europe regional plan — covers the UK plus 47+ European countries on one eSIM. From €9.49 for 5 GB / 45 days for a multi-country itinerary.

Either way, no per-day Brexit roaming surcharge, no carrier-imposed cap, and you keep your home SIM active for calls/SMS on your normal number. 5% Loyalty Points back into your Esimy Wallet on every plan.

How do I get an eSIM in the UK?

Buying an Esimy UK eSIM takes about 60 seconds and is fully online — no shop visits, no UK ID required, no UK address. Pick a plan on esimy.net (1 GB / 7 days at €1.99 for short trips up to 20 GB / 30 days at €14.99 for longer stays), pay by Visa, Mastercard, Apple Pay, Google Pay, or wire transfer, and the QR code arrives in your inbox within seconds. Install it before you fly: open Settings → Mobile Data → Add eSIM on iPhone, or Settings → Network → Mobile network → Add eSIM on Android, then scan the QR code. The eSIM sits dormant until you land — data starts the moment you toggle it on at Heathrow, Gatwick, Stansted, Luton, Manchester, Edinburgh, or any UK airport.

No queue at the EE / Vodafone / O2 / Three shop. No British passport or proof-of-address required. Coverage is on all four major UK networks (EE, Vodafone UK, O2, Three UK) for full nationwide 4G/5G — including Scotland, Wales, and Northern Ireland. 5% Loyalty Points back into your Esimy Wallet on every purchase.

What is an eSIM in the UK and how does it work?

An eSIM (embedded SIM) is a digital SIM profile built into your phone — no plastic card, no SIM tray. In the UK, all four major mobile networks support eSIM: EE, Vodafone UK, O2, and Three UK. The Esimy UK eSIM connects to these networks automatically when you arrive, giving you 4G/5G mobile data in London, Edinburgh, Manchester, Birmingham, Glasgow, Cardiff, Belfast, and across England, Scotland, Wales, and Northern Ireland.

How it works: you buy the plan on esimy.net, the QR code arrives in your inbox within seconds, you scan it on your phone (Settings → Mobile Data → Add eSIM on iPhone, or Settings → Network → Mobile network → Add eSIM on Android), and the eSIM sits dormant until you land at LHR, LGW, MAN, EDI, or any UK airport. Toggle it on, and you have data — no shop visit, no UK address needed, no SIM ejector. Your existing home SIM stays active so you keep your home number for calls and SMS. Plans from €1.99 / 1 GB / 7 days. 5% Loyalty Points back into your Esimy Wallet.

Do I need to present my identity when purchasing the eSIM to be activated?

No, the eSIM is activated exclusively online and it is KYC Free instantaneous activation with your name, surname, email, address and phone number, so there is no requirement of Identity.
