Quiz: How eSIMs Can Help You Save Money When You Travel

By dialing *#06# on your phone, you can see various identification numbers. If an EID (Embedded Identity Document) appears, your phone is eSIM-compatible.

You should review your most recent billing cycle to see how much data you typically use, divide it by the number of days in the month, then multiply by the number of days you’ll be traveling. This helps estimate your needs without overbuying.

Activating an eSIM requires internet access, and setup might involve scanning a QR code, clicking a link, or using a provider’s app. Because small airports may lack Wi-Fi, it’s safer to set everything up while still connected at home or in transit.

Once you’re home, go into your phone’s settings and disable or remove the eSIM profile. This ensures that you resume using your domestic carrier and won’t unknowingly use data or services through the travel eSIM.
