How a travel eSIM works
- 1Check your phoneIt has to support eSIM and not be locked to your carrier. Your phone's settings or your carrier can tell you.
- 2Buy and install before you flyPick a plan for Peru and install it at home on Wi-Fi: setting up an eSIM needs an internet connection.
- 3Switch it on when you landChoose the eSIM for mobile data and follow its setup notes; many ask you to turn on data roaming for that line.
- 4Keep your own numberYour home SIM can stay on for calls and texts. Many travel eSIMs are data only, with no local number, so check the plan.
