Most eSIM-capable phones can store several eSIM profiles, with typically one or two active at a time (both limits vary by model).

How to use them:

  • Install eSIMs for several countries in advance and switch the active line as you travel
  • Switch via iPhone "Settings → Cellular → select the line → Turn On This Line", or Android "Settings → Network & internet → SIMs"
  • After switching, also set Mobile Data to the eSIM you want to use

Note: if you delete an eSIM you're done with, remember it cannot be reinstalled. If data remains, it's safer to just turn it off.
