Yes! Most modern smartphones support dual-SIM functionality, which means you can keep your home mobile plan active for calls and SMS while using a DennisMobile eSIM for data. This way, you stay reachable on your regular number but enjoy affordable mobile internet abroad.
If your phone supports physical SIM + eSIM, your home plan must be on the physical SIM to use it alongside your DennisMobile eSIM.
If your device supports dual eSIMs, you can use both your home plan and DennisMobile eSIM together, regardless of whether your main plan is on a physical SIM or eSIM.
💡 Tip: Even if you disable your home SIM for calls and texts, apps like WhatsApp will continue to work with your regular number over your DennisMobile eSIM data connection.
