Anything we can give you a hand with?

Almost certainly. Practically every phone sold since 2019 takes an eSIM. The check that is always right takes ten seconds: open Settings, go to Mobile Data or Connections, and if you see "Add eSIM" or "Add Data Plan", you are fine.

For a week of maps, messaging and social media without video, 3 GB usually covers it. Streaming or sharing data with a laptop burns through it fast. We have a calculator that estimates it with honest numbers, and that recommends the smaller pack whenever it is enough.

The first time the eSIM attaches to a network, not when you buy it and not when you install it. You can buy up to 180 days before you fly, and not one day is spent waiting in your inbox.

No. The eSIM carries data only, which is what makes it cheap. Calls and text messages keep arriving on your usual line, which stays in the phone.

You get a QR code by email in under a minute. Open it on another screen — a computer, a tablet, a printed sheet — and scan it from your phone settings, under the option to add an eSIM. There is no app to install.

Yes, and we recommend it. Set it up calmly on your own wifi instead of fighting airport wifi with a queue behind you. Installing does not start the clock: that happens when it connects to a network on arrival.

Four things, in this order. One: turn on data roaming for the new line — without it nothing connects, and it costs nothing because the plan is already local. Two: go into Mobile Data and pick the eSIM as your data line, because the phone may still be using your usual one. Three: restart. Four: if it still will not connect, go to network selection and pick one manually. If none of that works, write to us.

No. Once installed, the eSIM stays on that phone. Install it on the one you are taking with you.

It cannot be installed again, and any data left on it is lost. That is why it is best left alone for the length of the trip.

It depends on the pack. The 33-country Europe pack keeps working across borders with nothing to change and no restart. Single-country packs stop carrying data the moment you leave that country.

Yes. The hotspot works the same as with any data plan, as long as your phone allows one. Bear in mind a laptop gets through far more data than a phone when you pick a pack size.

You can top up without reinstalling anything: the new data is added to the profile already on your phone, so there is no second QR to scan. You will need the email address you bought with.

Whatever the local network gives you, with 5G where the network has it. We do not throttle. Each country page lists the specific operators you connect to there.

Card, Apple Pay or Google Pay. Stripe processes the payment: your card details never pass through our site, we do not see them and we do not store them.

No. No sign-up, no password, no app. An email address to send the QR to, and that is it.

If we cannot issue your eSIM, the refund is automatic and complete. If it is issued and does not work through a fault of ours, we fix it or refund you. Write to us within the validity period.

You enter it on the site before paying, in the panel under the packs, next to the option to buy several eSIMs at once.
