United Kingdom eSIM — stay connected

eSIM is usually the better pick for United Kingdom if your phone supports it. Quick check: dial *#06# on your phone — if an EID number shows up, you're eSIM-ready, so install before you fly and skip the airport SIM counter. No EID? Go with RORO's physical SIM instead — same network, same top-up flow.

Note: a carrier-locked phone can't use RORO's eSIM or physical SIM either — it needs to be unlocked first. Full supported-device list is on our eSIM Compatibility Check page.

Head to the United Kingdom plan page on the RORO site or app, choose eSIM or physical SIM, pick a data plan, then check out with a card, PayPal, Apple Pay or Google Pay — no ID or local address needed. eSIM orders email you a QR code to install right away; physical SIM orders ship to your address, or can be collected at pickup points where available.

Not at purchase or install — the validity clock only starts once your RORO SIM connects to a network in United Kingdom. That means you can buy and install days or weeks ahead of your trip with no data wasted; it only counts down once you actually land and go online.

UK phones bought outright are unlocked by default; only some older contract phones are network-locked. Either way, RORO is a separate data-only eSIM, so it doesn't touch that lock — just confirm eSIM support.

Buy your United Kingdom plan, then scan the QR code we email you — on WiFi, using your phone's camera or the built-in eSIM setup screen. It installs in under a minute. Nothing activates yet: the validity clock only starts once your phone connects to a network in United Kingdom, so it's safe to install days or weeks ahead of your trip.

On arrival, turn off Airplane Mode, enable Data Roaming for the RORO line, and set it as your data SIM.

Coverage is strong across cities and mainline rail routes.

It depends on how you use your phone. Light use — maps, messaging, occasional browsing — a small fixed-GB plan sized to your trip length is usually enough. Streaming, video calls or heavy hotspot sharing call for a bigger tier or one of RORO's Unlimited plans, priced by day count instead of data.

Note: Unlimited plans include 3GB of high-speed data per 24 hours (from activation, resetting every 24 hours) plus a 500MB/24-hour hotspot-sharing allowance — if you need guaranteed high-speed data or unrestricted hotspot sharing throughout your trip, a Fixed plan is the safer pick. Check the current United Kingdom plans above for exact sizes and prices — since it's the same eSIM, you can always top up mid-trip rather than overbuying up front.

Yes, but a single-country plan only covers that country — it won't work once you cross the border. For a multi-country trip, buy a separate plan for each destination, choose one of RORO's regional bundles if your countries fall within one, or pick a Global plan for the widest coverage. You can hold multiple RORO eSIMs/physical SIMs at once and switch between them.

In fact, your RORO eSIM or physical SIM works across 190+ countries and regions worldwide — keep it installed after this trip and just top up with a new plan whenever you're heading somewhere else, no reinstall needed. A RORO SIM only expires after 2 years with no activity, and every top-up extends that validity by another 2 years.

Yes, but only after 2 years of no activity. A RORO eSIM or physical SIM doesn't expire the moment a data plan runs out or its validity period ends — it stays in your phone, ready to top up for your next trip.

Every time you top up with a new data plan, that 2-year countdown resets, so if you travel with RORO regularly the SIM effectively never expires. Only go 2 full years without a single top-up and the SIM itself expires.

Fixed plans give you a set amount of GB for your whole trip — a small pack is usually enough for maps, messaging and light browsing, and you can always top up if you run low. Unlimited plans are priced by day instead of data volume, but include 3GB of high-speed data per 24 hours (counted from activation and resetting every 24 hours) plus a 500MB/24-hour hotspot-sharing allowance — better if you stream or video call within those limits.

A single eSIM or physical SIM can hold multiple data plans, but only one is active at a time, in the order they expire — plans don't run side by side on the same SIM.

If you want an Unlimited plan but worry about hitting its 3GB high-speed cap, buy a separate Fixed plan on a second RORO eSIM: with both installed, switch to the Fixed-plan SIM once Unlimited's daily high-speed data runs out, then switch back after it resets. And if you plan to hotspot data to other devices or friends, a Fixed plan is the better pick, since Unlimited plans cap hotspot sharing at 500MB every 24 hours.

No. RORO can be bought and activated with just an email address — no passport copy, ID upload or local address required, unlike some local SIM registration rules in United Kingdom. Your payment method is all that's needed to check out.

Yes. RORO is a second, data-only line that runs alongside your existing SIM — it doesn't replace it. Most modern phones support two active lines (physical + eSIM, or dual eSIM), so you can keep your home number for calls and texts while RORO handles data in United Kingdom, with no data roaming charges from your home carrier.

Open the RORO app or site, pick another data pack for United Kingdom, and it's added straight to your existing eSIM — no new QR code, no reinstalling. Tip: top up before you hit zero. With no data left you can't get online to buy more, so you'd need WiFi to top up.

To top up: pick a data plan and hit Top Up, then enter the ICCID and PIN of the SIM you're adding it to — or start from your ICCID, choose which one to top up, then pick the plan. Either way, once payment goes through, the new data plan is added straight to that ICCID.

Yes. Uber and Bolt are the go-to ride-hailing option in United Kingdom, and booking or tracking a ride needs a live connection. For public transport, Trainline for intercity rail, and TfL Go or Citymapper for London's Tube and buses. Keep your RORO data on while you're moving around the city, not just at the hotel.

Yes — any RORO plan handles browsing and booking without trouble. Locally, Booking.com, Airbnb and lastminute.com are among the most-used platforms for hotels and attraction tickets in United Kingdom, alongside the usual global names.

RORO checkout accepts credit & debit cards (Visa, Mastercard, UnionPay), PayPal, Apple Pay and Google Pay, so you can buy your United Kingdom plan with whatever you already use at home.

On the ground, Contactless cards are the default nearly everywhere, with Apple Pay and Google Pay just as common. You generally don't need a local bank account to get by as a visitor — international cards and mobile wallets cover most tourist spending in United Kingdom.

999 or 112 (police, medical and fire). Save this before you land.

Emergency calls typically go through on any available network even without an active data SIM, but it's worth having RORO's data running for maps and messaging so you can describe your location clearly if needed.

Yes — share your RORO data with a laptop, tablet or a travel companion's phone via personal hotspot, the same as you would with a home SIM. No extra settings beyond turning on Hotspot on your phone.

Keep in mind the hotspot allowance depends on your plan: Fixed plans share their full data pool with no extra hotspot limit, while Unlimited plans cap hotspot sharing at 500MB every 24 hours. Speeds will follow local coverage, so hotspotting for heavy downloads works best in the cities and towns noted above.

The London Underground has patchy signal below ground on some older lines — it's fine the moment you're above ground, and coverage across the rest of the UK is consistently strong.
