Compare →Cost savings, instant activation, and zero roaming surprises — the business case for eSIM is now undeniable.
Read →An eSIM (embedded SIM) is a digital SIM card built directly into your device. Unlike a traditional physical SIM, it can be programmed remotely, allowing you to switch carriers and activate data plans without ever visiting a store or inserting a card.
For travelers, this is transformative. Instead of hunting for a local SIM at every destination, you can activate a regional data plan from your phone before you even board the plane. The technology is now supported by virtually every premium smartphone released since 2019.

An eSIM is a digital SIM card embedded directly into your device's hardware. Unlike a physical SIM card that you insert and remove, an eSIM is programmed remotely via a QR code or app. This means you can switch carriers or activate new data plans without physically handling any hardware — ideal for international travelers who need flexibility.
Most modern smartphones released after 2019 support eSIM, including iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and many others. The key requirement is that your device must be unlocked (not carrier-locked). Check our devices page for a complete compatibility list.
Yes. Many eSIM data plans are specifically designed for multi-country European travel. These regional plans cover the EU and EEA countries, allowing seamless connectivity as you cross borders. The roaming regulations within the EU also mean that many plans include roaming at no extra cost across member states.
eSIM activation typically takes between 2 and 5 minutes. After purchasing a plan, you receive a QR code by email. You scan this code in your phone's settings, the profile downloads, and you can enable it immediately. We recommend completing this process before departure so you're connected the moment you land.
