The Cost of Carrier Roaming

Major US carriers typically charge steep fees for international roaming. Options like AT&T's International Day Pass or Verizon's TravelPass cost around $10/day ($300/month). Unlocking your device allows you to bypass these fees entirely by using local network infrastructure.

Procuring a Travel eSIM

With an unlocked, eSIM-compatible device, traveling has become significantly easier.

  • Verify Unlock: Ensure your device displays "No SIM restrictions" or has completed an Android Network Unlock prior to departure.
  • Purchase Plan: Use platforms to purchase a prepaid data eSIM for your destination country.
  • Scan QR Code: Scan the provided QR code or use the provider's app to install the eSIM profile before boarding your flight.
  • Toggle Data: Upon landing, toggle off your home carrier's "Cellular Data Roaming" and switch your primary data line to the newly installed travel eSIM.

We recommend combining a travel eSIM for cheap, localized data while keeping your primary home carrier SIM active on Wi-Fi Calling to receive SMS/iMessage.
