on the Samsung A55, you can't have both your physical SIM and eSIM active simultaneously. The device supports dual SIM functionality, but it's a "hybrid" system. This means you can either use two physical SIMs, or one physical SIM and one eSIM, but not both physical SIM and eSIM at the same time.
You can't have both the physical SIM and the eSIM active at the same time.
You can choose which SIM is active at any time by toggling the switches in the SIM manager.
