1
Open Settings
Go to Settings > Cellular > Add eSIM (or "Add Cellular Plan" on older iOS).
2
Scan QR Code
Use your camera to scan the QR code from your EchoRoam email. If reading on the same phone, tap "Use QR Code" and select the screenshot from Photos.
3
Label Your Plan
Name it "EchoRoam" or "Travel Data" to distinguish from your home line.
4
Turn Off (For Now)
Keep the eSIM turned OFF until you arrive at your destination to preserve the validity period.
💡
iPhone tip: You can store multiple eSIMs but only use two at once (dual SIM). Delete old travel eSIMs after trips to free up slots.
