Can I use my physical SIM card and Billion Connect eSIM at the same time?

Yes! You absolutely can.

Most compatible devices support Dual SIM technology, allowing you to keep both your physical SIM and eSIM active simultaneously.

We highly recommend configuring your device to use your original physical SIM for phone calls and text messages (SMS) to keep your primary number reachable, while designating Billion Connect eSIM for mobile data (internet services) to enjoy affordable, high-speed roaming connectivity.
