Compared to international roaming, eSIMs offer affordable data plans tailored to specific regions or countries.

• Example Plan:
  • Airalo Europe Plan: 10GB for $35 (valid for 30 days).

D. Reduced Environmental Impact

eSIMs eliminate the need for plastic SIM cards, contributing to more sustainable travel practices.

E. Compatibility with Modern Devices

Most smartphones, tablets, and even wearables released in the past few years support eSIM functionality, making them accessible to a broad range of users.
