Does roaming with my Italian SIM work in the United Kingdom?

Technically yes, but watch out for the costs. After Brexit, the United Kingdom is no longer part of the European roaming area. Many Italian operators apply extra charges for data, calls and SMS on British territory. Before leaving, check your operator's plan — often a Datiovunque eSIM dedicated to the United Kingdom turns out to be much cheaper and free of nasty surprises on the bill.

Does the eSIM also work in Scotland, Wales and Northern Ireland?

Yes. The United Kingdom includes England, Scotland, Wales and Northern Ireland, and the coverage of operators such as EE and Three UK extends across the whole country. In the most remote parts of the Scottish Highlands or on islands such as Skye or Orkney the signal may drop to 4G in some areas, but in cities, towns and along the main transport routes the connection is stable and reliable.

Do I need an adapter to charge my phone in the United Kingdom?

Yes, absolutely. The United Kingdom uses Type G sockets — the ones with three flat rectangular pins — which are incompatible with Italian Type C/F plugs. It is essential to bring a universal adapter from home, since British sockets differ from any other in Europe. The voltage is 230V, so modern smartphone chargers are generally compatible, but without an adapter you cannot plug in.

Can I use the eSIM for calls too or only for data?

It depends on the plan chosen on Datiovunque. Most eSIMs for the United Kingdom include mobile data for browsing, using map apps, messaging and streaming. For traditional voice calls to British landline or mobile numbers, check the specifications of the plan you select. Alternatively, WhatsApp, FaceTime or other VoIP apps work perfectly with a good data connection.

How much does an eSIM for the United Kingdom cost?

eSIM plans for the United Kingdom start from €0.99. You pay once for the amount of data you choose — no subscription, no monthly fees and no hidden roaming charges. Plans with more data or longer validity cost more.

Which operator or network does the eSIM use in the United Kingdom?

The eSIM in the United Kingdom connects automatically to local networks such as EE, Three UK, Virgin Media O2, Vodafone, Three (VodafoneThree) — on 4G/LTE and, where available, 5G. Coverage reaches about 99% in inhabited areas. Your phone picks the best available network by itself.

Can I keep my Italian number with the eSIM in the United Kingdom?

Yes. Your Italian SIM and number stay active — the travel eSIM works alongside it as a data-only line. You stay reachable on WhatsApp, iMessage or Wi-Fi while you use the local network to browse. Traditional calls and SMS still go through your Italian number.

Should I activate the eSIM before or after I leave?

Install the eSIM at home, on Wi-Fi, before you leave. The data plan then activates automatically when you connect in the United Kingdom. That way you are online as soon as you arrive, without looking for airport Wi-Fi or buying a local SIM.

Can I top up or renew the plan for the United Kingdom?

Yes. When the data runs out or the validity expires, just buy a new plan — the eSIM profile already installed is kept and does not need to be installed again. You stay connected without interruption.

Can I share the connection (hotspot) in the United Kingdom?

Yes. You can share the connection in the United Kingdom through a personal hotspot with a computer, tablet or other devices. Shared data is deducted from your plan, so allow a few extra gigabytes if you expect to use the hotspot often.

How many GB do I need for the United Kingdom?

For a normal trip, 1–3 GB a week is enough for maps, messages and occasional browsing. With social media and photo sharing allow about 5 GB; for streaming, video calls or a hotspot count on 10 GB or more. If the volume is not enough, you can buy an additional plan at any time.

London absorbs you in an instant: the world's oldest underground, the Borough and Portobello markets, the historic pubs of Shoreditch and the free museums that swallow a whole afternoon. But the United Kingdom is also the cliffs of Cornwall, the Scottish Highlands wrapped in mist, the medieval lanes of York and the creative chaos of Manchester. Getting around here without internet means really getting lost — Citymapper is essential for surviving the Tube, bookings have to be made online and transport timetables change without notice. With a Datiovunque eSIM activated before you leave Rome, as soon as you land at Heathrow or Gatwick you are up and running — no queues, no kiosks, no physical SIM cards.

Why an eSIM is essential in the United Kingdom

After Brexit, the United Kingdom left the European "roam like at home" system: this means that most Italian operators charge significant extra for data use in Britain. What is free in France or Spain can cost money here — and the surprise lands, right on schedule, on your bill when you get back. A local eSIM dedicated to the United Kingdom removes this problem at the root. The operators EE, Three UK, Vodafone UK and O2 guarantee 99% coverage of the country with a 4G/LTE and 5G network, reaching not only London and big cities such as Birmingham, Edinburgh and Manchester, but also the rural areas of Wales, the Scottish islands and the most remote coasts. British time is UTC+0 — one hour behind Rome in winter, two hours in summer — so having working internet from the first moment is useful even just to reset your mental clock and let those waiting for news know you have landed. With Datiovunque, all of this is sorted before you even pack your bags.
