United Kingdom eSIM

Yes. Flylo eSIMs work across United Kingdom on the strongest local 4G/5G carriers, with automatic network fallover so you stay online in cities, airports, on trains, and in rural stretches.

Flylo is the cheapest unlimited eSIM for United Kingdom — guaranteed 5–10% cheaper than Holafly and Airalo on every plan. Install in 60 seconds, no SIM swap, no roaming bill.

Flylo United Kingdom eSIMs start at $5.55/day for unlimited data. Plans go from 1 day (great for layovers) to 30 days. Pick the duration that matches your trip — no overages, no per-MB billing.

Pick a plan above (1 to 30 days, all unlimited), pay with card, Apple Pay, Google Pay or PayPal, and the eSIM arrives by email in under a minute. No account hoops, no app forced on you.

Install the eSIM before you fly — it takes 60 seconds on a modern iPhone or Android. The eSIM activates the moment your phone connects to a tower in United Kingdom, typically as you taxi off the runway.

Yes — every Flylo plan runs at full 5G speeds in any region of United Kingdom where the local carrier supports it, and 4G LTE everywhere else. We don't throttle.

Yes — every Flylo unlimited plan includes hotspot / tethering. Share your data with travel companions, your laptop, or a backup phone at no extra cost.

Yes. Dual-SIM means your home line stays active for calls, SMS, WhatsApp, and two-factor codes; Flylo handles all your travel data while you're in United Kingdom.

Any eSIM-enabled phone works: iPhone XS / XR and newer, Google Pixel 3+, Samsung Galaxy S20 / Note 20 / Z Fold + Flip lines, and most flagship Androids from 2019 onwards. Check Settings → Cellular for "Add eSIM."

Flylo plans are data-only — but data is all you need. Use WhatsApp, iMessage, FaceTime, or Google Voice for calls and texts. Your home SIM still handles SMS / phone calls in parallel via dual-SIM.

No top-ups. Flylo eSIMs are a one-off purchase for the trip duration you chose. If you need more days, buy another plan from your account — it stacks onto the same eSIM profile.

Your United Kingdom eSIM is country-specific and stops working once you leave. For multi-country trips, buy our regional or global eSIM instead — same install flow, broader coverage.

Yes. eSIMs are encrypted by the GSMA standard and can't be cloned the way a physical SIM can. Your account is protected with magic-link login and Apple / Google sign-in — no passwords to leak.

Almost always: data roaming is off, or the wrong line is set as default for mobile data. Open Settings → Cellular, select your Flylo line, switch Data Roaming ON. If you're still stuck, email support@flylo.app — a real human replies within a few hours.
