United Kingdom (UK) travel data guide
A United Kingdom (UK) eSIM from RoamZivo is a prepaid data plan for United Kingdom (UK) that you install before you fly. Plans in United Kingdom (UK) run on O2, EE and 3, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 20 plans to choose from. Data sizes run from 1 GB to 50 GB, validity from 1 to 30 days, and prices start at $1.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on some of the fixed data plans and go onto the same eSIM.
Visiting more than one country? The Europe eSIM covers United Kingdom (UK) and 33 other countries on one plan, from $1.99. The Global eSIM covers United Kingdom (UK) and 126 other countries on one plan, from $18.99.
Your days start the first time the eSIM connects in United Kingdom (UK), not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in United Kingdom (UK) from RoamZivo arrives as a QR code by email, with a copy kept in your account.
United Kingdom (UK) FAQ
Does the eSIM work everywhere in United Kingdom (UK)?
It connects wherever O2, EE and 3 have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in United Kingdom (UK), not at purchase. The plan selected above (2 GB) runs for 15 days from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in United Kingdom (UK)?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
Which UK network does the eSIM use?
In the UK the eSIM connects to EE, O2 or 3, depending on the plan you buy. EE and O2 are listed with 5G and 3 is listed with 4G. The plan details are the place to check if you want a particular one.
Does the UK eSIM also work in Ireland?
No, the UK plan only works in the United Kingdom, and Ireland is not part of it. For a trip that takes in both, the Europe plan covers the UK and Ireland on one eSIM, along with 32 other countries.
Is there a large data plan for a month in the UK?
Yes, the UK has fixed plans of 30 GB, 50 GB and 200 GB that all last 30 days. A fixed plan has no daily slowdown, which is the reason to choose one over unlimited. Check that hotspot is allowed on the one you pick if a laptop will use it.
When do the days start on a UK eSIM?
The days start when the eSIM first connects to a network in the UK. Buying it and installing it at home do not use any of your time. A 7 day plan installed on Sunday and first used in London on Friday is counted from Friday.
How can I tell if my phone is carrier locked?
On an iPhone, open Settings, then General, then About, and look for the Carrier Lock line. If it says no SIM restrictions, the phone is unlocked and ready for a UK eSIM. On Android the quickest check is to ask the carrier that sold you the phone.
Can I use my phone as a hotspot in the UK?
Hotspot is allowed on some UK plans and not on others. If you need to share data with a laptop or another phone, look for it in the plan details before paying. The fixed plans of 30 GB and above are the ones worth checking first for laptop use.
Can I top up a UK eSIM when the data runs low?
Top up is available on some UK plans. Where it is not, you buy another plan and install the new QR code. Unlimited plans never reach zero. They slow to up to 1 Mbps once you pass 1 GB or 3 GB in a day.
How do I top up if I run low?
The plan selected above does not offer top ups. Buy a new plan from this page instead and install it as a second eSIM.
