Answer: Yes, absolutely. Thanks to Dual SIM technology, you can keep your physical SIM card active alongside your Cellesim eSIM.
Best Practice: We recommend setting your Physical SIM for "Calls and SMS" (to receive 2FA codes and urgent calls) and Cellesim for "Mobile Data". Warning: To avoid expensive roaming fees from your home carrier, ensure "Data Roaming" is turned OFF for your physical SIM.
