If an eSIM enabled phone has a physical SIM card in it that is being used for voice and SMS services, adding an eSIM data plan from a separate operator will not affect the existing voice and SMS services. However, it is possible that the device network settings may need to be adjusted to ensure that both the physical SIM and eSIM are able to function properly together.
Most modern smartphones support dual-SIM functionality which allows users to have two separate SIM cards active at the same time. With dual-SIM support you can use one SIM card for voice and SMS services and another SIM card for data services.
If you add one of our eSIM and data bundles, you will be able to use the eSIM for data services while still using the physical SIM for voice and SMS services. In summary the device settings need to enable data roaming services on the eSIM, disable data roaming services on the primary SIM, and leave voice and SMS services on the primary SIM.
It is important to note that the specific steps for configuring dual-SIM settings may vary depending on your device and mobile network provider. You should always refer to the instructions provided by your device provider for guidance.
