# Can I use my physical SIM card while using a Kurosim eSIM?

Whether you can use an eSIM and a SIM card at the same time depends on your device.

Devices that support this feature are those that offer options to manage two SIM cards, manage multiple plans, or add a second mobile plan.

Please note that Kurosim only provides data plans, which means that if you receive or make phone calls and send or receive text messages through your SIM card, you may be charged additional fees by your SIM card carrier.
