Can I use eSIM alongside my physical SIM (Dual SIM)?

Yes—most eSIM-compatible devices support Dual SIM, which allows you to use both an eSIM and a physical SIM at the same time.

How Dual SIM works

You can use:

• One SIM for mobile data (e.g. Ryoko eSIM)
• One SIM for calls and SMS (your primary SIM)

Common use case (travel)

• Use your Ryoko eSIM for affordable local data
• Keep your home SIM active for calls and messages

Important tips

• Disable data roaming on your primary SIM to avoid extra charges
• Make sure your Ryoko eSIM is selected for mobile data
• Label your SIMs (e.g. “Primary” and “Travel”) to avoid confusion
