Yes, you can install other eSIM profiles from other providers on your device along with the Ubigi eSIM profile. However, remember that even if you have several eSIM profiles, you can only use one at a time*.
*Except for some specific devices that don’t have a physical SIM tray and only support eSIM (ex: iPhone 14 models purchased in the United States don’t have a physical SIM tray and support only eSIM. One this specific device, you can use two eSIM profiles at the same time).
I have several Ubigi eSIM profiles installed in my device. Is it possible to have a unique Ubigi account to manage them all?
