Introduction
In this article, you will learn whether your primary phone number can receive calls while using both a physical SIM and an eSIM simultaneously, and what limitations may apply based on your device.
Before we start
- Check your device manual for Dual SIM compatibility and eSIM compatibility.
Can your primary phone number receive calls with both a SIM and an eSIM?
Yes, your primary phone number should be able to receive phone calls as long as your device supports simultaneous activation of both a physical SIM and an eSIM.
How does Dual SIM functionality work on iOS?
Particular iOS models support Dual SIM Dual Standby (DSDS) technology, which allows you to stay connected to both your physical SIM and eSIM at the same time. This means your primary number can receive incoming calls while both SIMs are active.
NOTE: The number of eSIMs you can have active on your device varies by model. Consult your device's manual or contact your device manufacturer for specific details about your iPhone's capabilities.
How does Dual SIM functionality work on Android?
Many modern Android smartphones support Dual SIM functionality with both physical SIM cards and eSIMs. Android devices with Dual SIM Dual Standby (DSDS) technology enable you to use both your physical SIM and eSIM simultaneously, allowing you to receive calls, send texts, and use data on both numbers.
NOTE: The exact number of eSIMs you can have active at once depends on your specific Android phone model and the version of Android it runs. Check your device's manual or contact your device manufacturer for details.
What additional charges might apply?
When using your own carrier alongside an eSIM service, additional data roaming charges may apply to the call service. Contact your carrier to understand any potential fees before activating both SIMs.
