UK eSIM prices
Data plans start at $2.99 for 1 GB valid 7 days, and unlimited plans start at $14.99 for 3 days. Everything is prepaid, data-only and bought in the app: no contract, no deposit, no credit check — and more plan sizes than most sellers carry, so you pay for the trip you are actually taking rather than the next size up.
Data plans
Match the bundle to the trip — the range runs from a light city-break allowance to a month of heavy use, with more steps in between than you will find on most shelves. Validity begins the first time the eSIM connects to a network in the UK, not on the day you pay for it.
| Data | Validity | Price | Price per GB |

| 1 GB | 7 days | $2.99 | $2.99/GB |
| 3 GB | 30 days | $5.99 | $2.00/GB |
| 5 GB | 30 days | $8.99 | $1.80/GB |

Unlimited plans
Unlimited plans have no total cap. After 3 GB at full speed in a single day the speed drops for the rest of that day and comes back the next morning — the plan's fair-use rule, printed here rather than hidden in a footnote.
| Validity | Price |
|---|---|
| 3 days | $14.99 |
| 5 days | $21.99 |
| 7 days | $29.99 |
| 10 days | $45.99 |
| 15 days | $68.99 |
| 30 days | $124.99 |

This page covers the United Kingdom only. If London is one stop on a longer European loop — Dublin, Paris, a rail pass through the continent — our Europe eSIM at europeesim.app covers the Republic of Ireland and the rest of the continent on one plan, so you are not buying a fresh eSIM at every border. Trip going further still, across a real mix of countries and continents? simtegre.com sells one eSIM across 200+ destinations worldwide, useful when the UK is just the first leg.
What every plan includes
5G and LTE on a national UK network — England, Scotland, Wales and Northern Ireland on the one plan.
Hotspot and tethering, included rather than sold as an add-on.
Top-ups that land on the eSIM already in the phone — no second install.
Your existing SIM keeps handling your number, calls and SMS codes. This plan does not hand you a UK number on top of it.
Pricing questions
How much does an eSIM for the UK cost?
Plans open at $2.99 for 1 GB, valid 7 days. A week's worth of maps, messages and the odd upload — leaning on hotel Wi-Fi overnight — typically comes to around $8.99. Unlimited plans start from $14.99.
Is an eSIM cheaper than roaming in the UK?
Two different answers. From the EU: Brexit ended Britain's place in the roam-like-at-home scheme, and most European carriers have since brought back UK roaming charges or daily passes — the free allowance your last trip to Spain used probably does not apply here, so check your tariff before assuming. From everywhere else, the UK was always billed as international roaming. Either way, put your carrier's rate next to a plan here: a larger bundle is $21.99 for 15 days, paid once.
Are there hidden fees?
No. What is on screen is the entire price — no activation fee, no deposit, no monthly charge, no auto-renewal, and nothing tacked on at checkout. The app itself costs nothing, and a plan simply runs out rather than rolling over.
Which plan should I choose?
A city break with hotel Wi-Fi at night mostly means maps, messages and the odd photo upload — a light plan covers it. Go bigger if you are working off the phone, sharing a hotspot with the family, or driving between sights with navigation running all day. Take unlimited if you would rather not calculate it at all.
