In 2026, activating mobile data no longer involves searching for a clip to open the phone's SIM tray. eSIM allows you to set up a line in minutes by scanning a QR code. It's a solid option as a primary line, a secondary line for traveling without paying traditional carriers' roaming fees, or as an additional work line. Providers like Holafly, Airalo, or Saily offer rates from 3 euros per day, far from the 15-25 euros a SIM costs at airports.
Compatibility and reliability of the eSIM standard 📶
eSIM technology is a mature and reliable standard. It is compatible with iPhones from the XS onwards, Google Pixels from the fourth generation, and Galaxy S20 and later. Its operation is based on an integrated chip that stores the carrier profile, eliminating wear and tear and the loss of the physical card. Remote activation via QR or app is immediate, and it allows managing multiple lines without changing SIMs, offering flexibility that traditional carriers are only just beginning to match.
Goodbye to the clip and airport queues ✈️
You'll fondly remember those glorious moments of trying not to lose the tiny SIM on a carpet while sweating in the arrivals terminal. Now, with eSIM, you pay three euros from your couch and activate the data before the plane lands. Very convenient, yes, but watch out: if you lose your phone, your low-cost travel plan becomes a high-end problem. At least you won't have to argue with the airport shop assistant about whether your iPhone is compatible anymore.
