eSIM technology is revolutionizing how we travel. Gone are the days of hunting for a local SIM card vendor at the airport or paying exorbitant roaming fees to your home carrier.

What is an eSIM?

An eSIM (embedded SIM) is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM. Built directly into your device, it offers unparalleled convenience and flexibility.

Why use an eSIM for travel?

  • Instant Activation: Purchase and activate your data plan before you even board the plane.
  • Keep Your Number: Use your physical SIM for calls and texts while using the eSIM for data.
  • Cost Savings: Avoid roaming charges that can cost upwards of $10/day.
