Convert a Physical SIM to an eSIM: Step-by-Step Guide

Should You Convert Your Physical SIM to an eSIM?

An eSIM functions just like a physical SIM card but how exactly does it work, and why might it be the better choice? Here are the main advantages an eSIM offers compared to a traditional plastic SIM:

• Easy setup

Activating an eSIM takes just a few taps on your phone. No need to purchase a physical card or handle tiny trays that risk damage during installation.

• Multiple profiles on one device

Many eSIM-compatible devices support dual SIM functionality. You can store several eSIM profiles and switch between them whenever needed.

• Convenient for international travel

Instead of hunting for a local SIM card and navigating language barriers to set it up, you can simply download an app, choose a local plan, and get connected instantly without leaving your hotel room.

In addition, using an eSIM helps reduce plastic waste and frees up space in device design by eliminating the need for a physical SIM slot though these are secondary benefits compared to the core advantages listed above.

How to Find Out if You Can Convert Your Existing SIM to an eSIM

• Contact your carrier: Your mobile provider can confirm if your number and device are eligible for eSIM conversion.
• Look up your phone model: Find your phone model in a supported devices list to verify eSIM compatibility.

If your device supports eSIM and your carrier allows conversion, switching is usually quick and straightforward. It saves time and removes the need for a physical SIM altogether.

Many carriers in the U.S like US Mobile and T-Mobile offer travel eSIMs that can be activated instantly by scanning a QR code. It’s a fast and hassle-free process. Others, such as Verizon, require activation through their official mobile app.

Will Converting a SIM to an eSIM Hurt Your Wallet?

In most cases, converting a physical SIM to an eSIM is free. An eSIM isn’t just easy to activate - it’s often the smarter choice for your wallet, especially when you're on the move.

Is There a Fee for Switching From a Regular SIM to an eSIM?

A common concern when switching to an eSIM is whether there’s a cost involved. In most cases, mobile carriers do not charge a fee for converting from a physical SIM to an eSIM. If there is a charge, it’s usually minimal - typically between $5 and $10.

Before starting the process, contact your carrier to confirm whether a fee applies. Also, ask if the cost will appear on your next bill or needs to be paid upfront.

Can You Use Both an eSIM and a Regular SIM at the Same Time?

Yes, you can. Most smartphones that support eSIM also come with dual SIM functionality, which means you can use both a physical SIM and an eSIM at once. This allows for flexibility - like keeping your primary number active while using a travel eSIM for data.

Dual SIM is especially useful if you want to:

• Use one line for calls and texts (physical SIM)
• Use the other for mobile data (eSIM)
• Switch between personal and work numbers easily
• Stay connected abroad without paying high roaming fees

Some newer smartphones like the latest iPhone models - no longer have a physical SIM slot and support eSIM only. While this isn’t yet the norm, it’s becoming more common in newer devices.

If you're traveling internationally, using an eSIM from providers like BitJoy is a convenient and cost-effective way to stay connected. You can activate it instantly and avoid roaming charges.

H2: Are There Any Disadvantages to Switching to an eSIM?

While eSIMs offer great benefits, they do come with a few limitations to keep in mind.

• Device compatibility: Many newer smartphones support eSIM, but older models typically do not. Always check your phone’s settings or the manufacturer's official list to confirm compatibility.
• Carrier support: Not all mobile carriers offer eSIM services. Even if they do, some may charge a small fee for activation or switching.
• Limited accessibility: In some regions, eSIM adoption is still growing, and the availability may vary depending on your location and provider.

Despite these drawbacks, eSIMs remain a convenient and future-ready option—especially useful for travelers who want flexibility without the hassle of swapping SIM cards.

What Happens to a Physical SIM After Converting to an eSIM?

Once you switch to an eSIM, your physical SIM doesn’t automatically become obsolete—it depends on how you want to use it.

You can:

• Keep the SIM card in your phone as a backup.
• Use it for specific functions like mobile data or SMS (if your phone supports dual SIM).
• Remove and deactivate it completely if you no longer need it.

In any case, it’s important to notify your mobile carrier about the change to ensure proper service configuration. Some users prefer to keep their physical SIM as a fallback in case of eSIM issues. Others choose to remove it to avoid confusion or free up the SIM slot for travel use. Your choice should depend on your connectivity needs and device setup.

Can an eSIM Be Converted Back to a Physical SIM?

Yes, it is possible to convert an eSIM back to a physical SIM card, but this can’t be done independently. You’ll need to contact your carrier and inform them of your request. They will guide you through the process to make the switch.

Alternatively, you can purchase a new physical SIM card from your preferred vendor and install it manually. However, the eSIM will not be removed automatically unless you request deactivation from your carrier.

Keep in mind, while you can switch between eSIM and a physical SIM, it’s always best to verify with your carrier regarding their specific procedures for deactivation and activation.
