eSIM explained: how it works and who it suits
Short answer
An eSIM is a SIM card built into your phone. Instead of inserting a plastic card, you scan a QR code or activate it in your provider's app. It makes switching providers and using two numbers easier, and travel data plans can be added in minutes.
Advantages
You can set up a new contract or travel plan without waiting for a card in the post. Most phones can hold several eSIM profiles and use two numbers at the same time, for example private and work.
- No card to lose or swap
- Two numbers on one phone
- Cheap travel data plans outside the EU
Things to know
Moving an eSIM to a new phone usually works via the phone's transfer function or a new QR code from your provider. Some providers charge a small fee for a new eSIM profile. Some newer phones, such as the iPhone Air, work only with eSIM and have no SIM tray at all.
Do all providers support it?
All major networks in Germany, Belgium and the Netherlands offer eSIM, and most budget brands now do too. Check your provider's website before switching.
Questions and answers
Can I use an eSIM and a physical SIM at the same time?
Yes, on most modern phones. You can also use two eSIMs on many models.
What happens to my eSIM if I lose my phone?
Contact your provider. They block the old profile and send you a new eSIM to activate on your replacement phone.
