Yes, absolutely. Thanks to the dual SIM functionality in most modern smartphones, you can keep your existing physical SIM card active alongside your eSIM Trails plan. This allows you to receive calls or texts on your primary number while using the eSIM Trails data for internet connectivity. We often recommend setting your physical SIM for calls and SMS only, and designating your eSIM Trails for all data, optimizing your connection for reliable data access on the trails.
