An eSIM lets you get online the moment you land — no plastic SIM, no roaming bills, no hunting for a local shop. Here is how to pick the right plan for your next trip.

1. Check coverage first

Before price, confirm the plan covers every country on your itinerary. Regional plans are great for multi-country trips, while a single-country plan is usually cheaper if you stay in one place.

2. Match the data to how you travel

  • Light use (maps, messaging): 1–3 GB.
  • Regular use (social, browsing): 5–10 GB.
  • Heavy use (video, tethering): 20 GB or unlimited.

3. Activate before you fly

Install the eSIM at home over Wi-Fi and set it to activate on first connection abroad. You will be online as soon as your plane lands.
