Can I use both an eSIM and a physical SIM with the same number? #

At Gohub, we understand that navigating the world of eSIMs and dual SIM functionality can sometimes be confusing. That’s why we’re here to clarify the key differences and help you maximize your device’s capabilities.

Many of our customers ask us about using both physical SIMs and eSIMs, particularly when it comes to using the same phone number. Let’s break down the fundamentals:

Dual SIM Functionality: Two Numbers, One Device #

Modern smartphones are increasingly equipped with dual SIM capabilities. This means your device can simultaneously support two active SIM profiles. These profiles can be a combination of:

  • A physical SIM card and an eSIM: This is the most common configuration.
  • Two eSIMs: Newer devices are increasingly offering this option.

The key benefit of dual SIM is the ability to use two distinct phone numbers on a single device. This offers numerous advantages:

  • Separating Personal and Work: Keep your professional and personal lives separate by using different numbers for each.
  • Travel Convenience: Use a local Gohub eSIM for affordable data while traveling, while maintaining your primary number for calls and texts. This avoids hefty roaming charges.
The Crucial Distinction: Same Number, One SIM at a Time #

It’s vital to understand that while you can have two SIMs active, you cannot have the exact same phone number actively working on both a physical SIM and an eSIM at the same time.

Here’s what you can do:

  • Convert Physical SIM to eSIM: You can transfer your existing physical SIM number to an eSIM. This effectively deactivates the physical SIM, as the number is now associated with the eSIM profile.
  • Transfer eSIM to Physical SIM: In some cases, depending on your carrier, you can move a number from an eSIM back to a physical SIM.

Essentially, your phone number is exclusively linked to one SIM profile at any given moment, whether it’s a physical SIM or an eSIM.

In Summary #

  • Your dual-SIM phone allows you to use both a physical SIM and an eSIM.
  • You cannot use the same phone number on both a physical SIM and an eSIM simultaneously.

We hope this explanation clarifies how dual SIM functionality works and helps you make the most of your device. If you have any further questions about eSIMs or our services, don’t hesitate to contact our Gohub customer support team. We’re here to help you stay connected, wherever you go.
