An eSIM is a digital SIM built into your phone. Instead of swapping a plastic card, you add a mobile plan by scanning a QR code, and your phone connects to a local network at your destination.

Most phones released since 2018 do, but your phone also has to be carrier-unlocked. Dial *#06# and look for an EID number, or look for an “Add eSIM” option in your settings. You can also browse our full list on the compatible devices page.

Your QR code and setup instructions are sent to the email address you used at checkout. Keep that email safe, because you will need the QR code to install the eSIM.

• iPhone: Settings, Cellular (or Mobile Data), Add eSIM, then Use QR Code.
• Android: Settings, Network & internet, SIMs, then Add eSIM. Menu names vary a little by brand.

Follow the prompts, then wait for the installation to finish.

Yes, and it is a good idea. Install it at home on Wi-Fi so everything is ready when you land. Most plans only start counting down once the eSIM connects to a network at your destination, but check the details on your plan’s page.

Your plan’s validity period begins when it first connects to a network in the country you are visiting, not when you buy it. The data amount and number of days are shown on each plan before you check out.

Yes. An eSIM works alongside your regular SIM, so keep your home SIM in the phone and set the eSIM as your mobile data line. Travel eSIMs are usually data-only, so for voice calls and texts use apps like WhatsApp, FaceTime or Messenger.

In most cases, yes. Switch on Data Roaming for the travel eSIM line only, and set that line as your mobile data line. Leave roaming off for your home SIM to avoid charges from your home carrier.

Most plans allow tethering, so you can share data with a laptop or a travel companion. Check your plan’s details if hotspot use is important to you.

On your phone, open Settings, then Cellular or Mobile Data, and look at the usage listed under your travel eSIM line.

Your connection will stop or slow down once the allowance is used up. You can buy another plan for the same destination and install it the same way.

An eSIM is designed to be installed on one device only. Once it is installed, it cannot be scanned onto a second phone. If you delete it from your phone, it usually cannot be reinstalled, so only remove it when you are finished with it.

• Make sure the travel eSIM is switched on and selected as your mobile data line.
• Turn on Data Roaming for that eSIM line.
• Restart your phone, or toggle Airplane Mode on and off.
• Confirm your phone is carrier-unlocked.
• Make sure you are in the country your plan covers.

Because eSIMs are digital products, refund eligibility depends on whether the eSIM has been installed or used. Please read our Terms of Service, or contact us before installing if something is not right.
