On iOS devices, you can download up to 8 eSIM profiles, but only 2 eSIMs can be active at the same time (for iPhone 13 and later). You can switch between active profiles in Settings > Mobile Service.
On Android devices, the number of eSIMs you can install and activate varies by model. Please check your device specifications for more details.
As a best practice, we also recommend deleting any old or expired eSIMs if you have multiple eSIMs on your device, and renaming your eSIM in your device settings to avoid confusion.
