Wat is een eSIM?
Last updated Juni 2026
Een eSIM (embedded SIM) is een digitale SIM-kaart die rechtstreeks in uw telefoon is ingebouwd. In plaats van een plastic kaart te plaatsen, downloadt u een mobiel abonnement via de lucht - wat het perfect maakt voor reizen.
eSIM, in één minuut uitgelegd
Traditional SIM cards are tiny plastic chips you physically insert into your phone. An eSIM does the same job - identifying you to a mobile network - but it's a reprogrammable chip soldered inside your device. You can download a new plan onto it in seconds, switch between plans, and keep several stored at once. Nothing to insert, nothing to lose.
How does an eSIM work for travel?
Before your trip, you buy a travel data plan from a provider like SimFuse and install the eSIM over Wi-Fi - either by scanning a QR code or through the app. Your home SIM stays in the phone for calls and texts, while the travel eSIM handles your data. When you land, the eSIM connects to a local partner network automatically, so you're online without roaming charges or a trip to a SIM shop.
What are the benefits of an eSIM?
eSIMs are faster to set up, impossible to lose, and let you keep your home number active. You can buy and install before you travel, hold multiple plans for different countries, and top up instantly. For international travel specifically, an eSIM avoids both expensive roaming and the hassle of buying a local SIM at the airport.
Does my phone support eSIM?
Most phones released since 2018 do - including iPhone XS/XR and newer, recent Samsung Galaxy, Google Pixel and many others. Your phone also needs to be carrier-unlocked. See our eSIM-compatible phones guide for the full list, or our step-by-step install guide.
