The number of Saily eSIMs you can install and use simultaneously depends on your device. In fact, some iPhones support up to ten eSIM profiles, while most Android devices support up to seven eSIMs.
However, keep in mind that the number of installations doesn't equate to active usage. Typically, you can only actively use up to two eSIMs at a time.
It's also worth noting that you could simply use one eSIM for your location and top it up with a destination data plan when needed.
Additionally, getting a new eSIM can be useful if you want to manage multiple eSIMs across devices under the same account.
