How Does an eSIM Work, and What Does It Do?

A SIM card that's embedded in your device is called an eSIM. It connects to your cellular network without needing a physical SIM card. So, you won't have to worry about card holders, SIM card slot pins, or changing your physical SIM if a problem occurs. 

eSIMs work just like SIM cards. They have the same practical use but without a physical presence. Plus, eSIMs come pre-installed on your device, so you don't have to buy them from a network provider. 

But how do these eSIMs work? Let's find out. 

How to Use an eSIM?

As mentioned, you can activate your eSIM on your own or ask your network provider to do it for you. Usually, the latter approach is used. 

To activate different carrier plans, you can buy an eSIM data plan and use your cellular services. You can also use multiple carriers on the same eSIM and subscribe to several data plans simultaneously. 

Plus, you won't have to switch to a new network if you want an eSIM plan from a different carrier service when traveling abroad. That way, you can avoid hefty roaming data charges when traveling internationally. 

You can also directly contact your carrier service and subscribe to an international plan within seconds. 

How Does an eSIM Help When Traveling? 

Changing to a different network when traveling is very useful. You won't have to worry about changing SIMs, so you don't spend too much on roaming services when abroad. 

Plus, using an eSIM, you can switch back and forth between networks without having to go through the hassle of fiddling around with a physical SIM. 

How to Set Up Your eSIM?

To set up your eSIM, you'll have to check if your device supports the technology and your network carrier supports it. 

After verifying this information, contact your wireless carrier to get a QR code or an activation code:

  1. Open the "Cellular" or "Mobile Data" tab in your settings. 
  2. Scan the QR code or insert the activation code provided by your cellular service. 
  3. Follow the on-screen instructions to activate the eSIM.

Can I Use an eSIM with a Physical SIM? 

Yes. Most mobile devices come with both options. You can also change the settings and set the SIM card you want to use for making calls, messages, or using the internet.
