Plan your connection

Choose a UK eSIM for your visit

Use prepaid mobile data for maps, rail apps and messages across the United Kingdom. Compare fixed 1–10GB plans with daily options that include 3GB of high-speed data.

Fixed data or a daily reset

Fixed plans provide one allowance over 7 or 30 days. Daily plans run for 1–15 days, include 3GB of high-speed data each day, and continue at up to 1 Mbps until the next daily reset.

O2, EE and Three network access

Current plans list O2 and EE with 5G and Three with 4G. The actual connection depends on supported bands, your device, exact location and local network conditions.

Destination questions

Does the UK eSIM include a UK number?

No. It is data-only and does not include a UK phone number, calls or SMS. Keep your primary SIM installed if you need to receive service from your usual number.

Should I choose UK-only or Europe 33?

Choose UK-only for a trip contained within the United Kingdom. Compare Europe 33 when crossing into another listed destination, and check the full coverage before checkout.

Questions about this eSIM?

The selected plan details above are the source of truth for your package.

When does validity start?
For this catalog, validity starts when the eSIM first connects to a supported network. Check the selected plan details above.
Can I install before my trip?
Yes. Current plans allow installation up to 180 days before travel. Installation alone does not start validity; the first supported-network connection does.
Can I keep my primary SIM?
Yes. Keep your primary SIM for calls or messages and select RoamUno for mobile data. Check your phone settings to avoid roaming charges on the primary line.
Does this include calls or SMS?
RoamUno travel plans are data-only and do not include a phone number, voice calls or SMS unless the product explicitly says otherwise.
When will I receive the eSIM?
Installation details are sent by email after confirmed payment and order checks. Risk review or a supplier delay can take longer.
