Can I Use My eSIM as a Dual SIM?

Yes, you can use your eSIM as a Dual SIM if your phone supports this functionality. Dual SIM capability allows you to have both a physical SIM and an eSIM active simultaneously. It’s crucial to verify that your device supports Dual SIM with eSIM, as not all Dual SIM devices are eSIM compatible. Check your phone’s technical specifications and confirm compatibility with your carrier. In this article, you’ll discover more about the benefits of using an eSIM as Dual SIM and some setup tips. Keep reading to explore everything you need to know!

Benefits of Using Dual SIM with an eSIM:

Using this function offers flexibility and convenience, especially for frequent travelers:

  • Keep your local number active while using an international plan on your eSIM. 
  • Manage two numbers on one device without needing multiple phones.
  • Switch easily between carriers, ideal for accessing better rates or avoiding roaming charges.

To Keep in mind

  • Verify that your phone supports Dual SIM with eSIM technology.
  • Manually assign each SIM for specific tasks, such as one for calls and the other for data.
  • Some networks may not support simultaneous use of both SIMs in all regions.
  • Only one SIM can use mobile data at a time.
  • Plans and top-ups for each SIM must be managed separately.
  • Keeping the primary SIM active while traveling abroad will result in roaming charges from your main carrier.
  • Using two carriers requires an unlocked device.

Troubleshooting Tips

To avoid roaming charges for data with your carrier, label your SIMs, use one for calls and the other for data. Keep your physical SIM for calls and an eSIM like Holafly for mobile data. Also, disable mobile data switching to use only Holafly’s data.
