What Is an eSIM and How Does It Work?

You land in a new country, turn on your phone, and get hit with a $15 roaming charge before you even open a map. An eSIM stops that from happening.

An eSIM is a digital SIM built into your phone. You scan a QR code, download a plan, and connect to a local network in minutes. No plastic card, no store visit.

  • Works on iPhone XS and newer, plus most modern Android phones
  • You can store 5 to 8 eSIM profiles at once
  • Activation usually takes under 5 minutes
  • Most travel eSIMs are data-only, so you keep your home number

If your phone is unlocked and on the compatibility list, you are ready to travel without roaming fees.
