Frequently asked questions.
Everything travellers ask before, during and after a trip.
An eSIM is a digital SIM already built into your phone. Instead of swapping a plastic card, you scan a QR code and a travel data plan installs in about two minutes — your home SIM stays in place.
Most phones from 2018 onwards support eSIM — iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and many more. Use our compatibility checker to be sure before you buy.
Install at home on Wi-Fi before you fly — it takes two minutes. Your days only start counting when the eSIM connects to a network at your destination.
Yes. WhatsApp stays tied to your home number even while your data comes through My Holiday SIM. Nothing to re-verify, no missed messages.
Your holiday plans are unlimited — no caps, no surprise charges. If your trip runs longer than planned, top up extra days from your account in a few taps.
Never. You pay one clear price per day before you travel. That is the whole bill.
Hotspot and tethering are included on plans where the local network allows it — the plan card tells you before you buy.
If your eSIM has not been installed and your plan has not started, we refund in full within 30 days of purchase. Full details in our refund policy.
All prices are shown in British pounds (GBP) today, with no hidden fees — you pay exactly what you see. More display currencies (USD, EUR and others) are on the way.
Yes — enter their email at checkout and the QR code goes straight to them. Great for parents and less techy travellers.
Yes, installation downloads the eSIM profile so a connection is needed — home Wi-Fi is ideal. That’s why we recommend installing before you fly.
Just switch the line on when you land. The eSIM finds a partner network automatically and your days start at first connection.
Yes — any Wi-Fi (hotel, café, airport) works for the 2-minute install. Buying from abroad is fine too.
Yes, wherever the local partner network permits it — the plan page confirms before you buy. Share to laptops, tablets and travel buddies.
From your account, pick the active eSIM and add days. The extension starts when your current days finish, so nothing overlaps or is lost.
First, support will troubleshoot with you — it’s almost always a settings toggle. If there’s a genuine fault on our side, you get a full refund or replacement. Always.
Travel eSIMs connect to partner networks abroad, which phones label as roaming. On our plans that switch never adds charges — the price you paid is final.
Try manually selecting another partner network (Settings → network selection), move away from crowded areas, or toggle aeroplane mode. 5G appears automatically where available.
No — guest checkout works with just an email. An account adds order history, faster top-ups and (soon) the app.
iOS and Android apps are in development. Join the waitlist on the App page for early access and a launch-week top-up credit.
