An eSIM is an embedded digital SIM—you install a profile by QR code or activation details instead of swapping plastic. It is ideal for travel data and dual-line setups if your phone supports it.

Pros and cons

  • Pros: remote activation, multiple profiles, no lost nano-SIM, easy dual-SIM travel.
  • Cons: not every handset supports eSIM; profiles usually cannot move to another phone; first setup needs Wi-Fi.

Check support first

iPhone XS / XR and newer typically support eSIM. Android varies by brand—look under Network & internet / SIMs for “Add eSIM”. Confirm the phone is carrier-unlocked.

Install in minutes

  1. Buy a travel eSIM and save the QR / SM-DP+ details
  2. On Wi-Fi: Settings → Cellular / Mobile network → Add eSIM → scan
  3. Label the line (e.g. “Japan eSIM”); keep home line for SMS
  4. After landing, switch mobile data to the travel eSIM; follow the product page on data roaming

Do not delete the profile if it fails to connect—toggle airplane mode, restart, then contact support with your order ID.
