It connects to O2 (5G), EE (5G) and 3 (4G), and the eSIM uses whichever of them has the best signal where you are.
Which regional eSIM also covers United Kingdom?
Two regional eSIMs cover the United Kingdom as well: the Europe eSIM from US$3.40 (up to 43 countries) and the Global eSIM from US$11.90 (up to 129 countries). Each covers several countries on one plan, handy if the trip also takes in Ireland or Norway.
Can I share the United Kingdom eSIM data by hotspot?
Yes, on the daily plans, from US$2.80 a day; hotspot use counts toward the same daily allowance.
When do the days start on the United Kingdom eSIM?
On first connection in the United Kingdom, not at purchase or install. Install it on wifi before you fly, up to 180 days after buying. The 100MB (7 days) plan is an exception: its validity starts the moment you install it, not on first connection, so install it only when you are ready to start using the data.
Can I make calls with the United Kingdom eSIM?
No, it is data only, with no United Kingdom number: WhatsApp and FaceTime calls work over the data.
Where does the United Kingdom eSIM connect to the internet from?
From France, the Netherlands or the United Kingdom, so apps may see you there rather than in the United Kingdom, which mostly matters to banking and streaming.
Heading somewhere else?
One eSIM can cover a whole region, handy for multi-country trips.
