Phone Data Abroad: Why a Travel eSIM Beats Roaming Fees

International roaming plans from US carriers can cost a lot per day. A travel eSIM gives you local data for a fraction of that, as long as your phone supports it.

What an eSIM is

An eSIM is a digital SIM card built into most recent phones. You buy a data plan for the country or region you are visiting, install it by scanning a QR code, and switch your data to it when you land. Your regular number can stay active for calls and texts if you need it.

Check before you buy

  • Your phone supports eSIM (most recent iPhones and many Android phones do).
  • Your phone is unlocked, so it can use a plan from another provider.
  • The plan covers every country on your trip, or choose a regional plan.

Set it up at home

Install the eSIM over Wi-Fi before you leave, then turn it on when you arrive. Turn off data roaming on your main line so you do not get charged by accident.

How much data you need

Maps, messaging and light browsing use little data. Video streaming and hotspotting use a lot. For a one-week trip with normal use, a few gigabytes is usually plenty.
