You normally have the possibility in eSIM compatible devices to install several eSIM profiles at the same time, even if they are from different operators. This means that you do not necessarily need to delete an eSIM profile to install another one on the same device.
However, be aware that even if you have more than one eSIM profile installed on your device, you can only use one at a time.
You can switch from one installed eSIM profile to another in the Settings of your device.
