​No, purchasing and adding another Olysim eSIM to your device will not affect any physical SIM or other eSIMs already installed on your device. eSIM-compatible devices allow you to store multiple eSIM profiles and switch them on or off as needed.

Your Olysim eSIM and plan will function independently of your existing physical SIMs or eSIMs. This is one of the main benefits of eSIM technology—it offers the flexibility to manage multiple eSIM profiles on a single device to meet your connectivity needs.

Currently, iOS allows you to download up to 8 eSIM profiles on your device, but you may only have up to 2 active eSIM profiles (for iPhone 11 and later) at one time. You can switch which eSIM profile is active under your iOS Settings > Cellular.

On Android devices, then number of eSIM profiles that you can have installed and the number of active eSIMs you can have vary from device to device. Please check your device specs for more information.
