Installing an eSIM takes about a minute. The golden rule: do it on Wi-Fi before you travel, because downloading the profile needs an internet connection.
On iPhone: Settings → Mobile Service → Add eSIM → Use QR Code, then scan the code from your GlobalSimify dashboard. Label it “Travel” and turn on Data Roaming for that line when you arrive.
On Android: Settings → Network & internet → SIMs → Add eSIM, scan the QR, then set the eSIM as your mobile-data SIM abroad and enable roaming for it.
You can install the eSIM on Wi-Fi before travelling. Data validity follows the travel dates selected at checkout; check your confirmed order dates.
