The process of converting to an eSIM is surprisingly straightforward and offers a host of benefits, including freeing up your device's SIM slot for dual-SIM functionality and added convenience when switching between networks. Whether you're a frequent traveller, a tech enthusiast, or someone who simply values convenience, switching to an eSIM can enhance your mobile experience.

In this blog, we'll walk you through the step-by-step process of converting your physical SIM to an eSIM. But first, let's explore who this switch is best suited for and who might want to think twice before making the change.

Is switching to an eSIM right for you?

Switching to an eSIM does have its shortcomings like it is compatible only with selective carriers and might offer limited support in regions where eSIM technology is still emerging. However, that said, eSIMs are still comparatively ideal if:

• You own a compatible device ready to support this technology.

• You want seamless international travel, as you can switch to a local network without buying local SIM cards. 

• You need easy access to local or temporary plans.

• You want dual-SIM functionality on a single device.

• You prefer a secure and clutter-free solution.

In the sections ahead, we'll explain how to make the switch and what to keep in mind to ensure a seamless transition. Let's dive in!

What to do with your physical SIM after conversion?

Once your eSIM is active, your physical SIM card will no longer be needed for the same number. You can:

• Keep it as a backup: Store your physical SIM card safely in case you need it for a device that doesn't support eSIM.

• Dispose of it properly: Recycle the physical SIM card responsibly to minimise electronic waste.

Troubleshooting common issues during physical SIM to eSIM conversion

While the process of converting a physical SIM to an eSIM is typically straightforward, some might encounter occasional challenges that may interrupt the flow. These hiccups can range from technical glitches to compatibility issues, but most problems have pretty simple fixes. 

1. QR code not scanning

The most common issue during eSIM activation involves the QR code. Here are a few tips to address it:

• Clean your device's camera lens for a clear capture.

• Ensure the QR code is not damaged or blurry. If it's on paper, check for creases or smudges.

• Scan the QR code in a well-lit area to help your camera focus.

• And if the QR code still fails, enter the activation details manually using the provided code.

2. eSIM activation failed!

If your eSIM activation doesn't complete successfully, try these steps:

• Restart your phone, as it often resolves temporary software glitches.

• Ensure your device has the latest software update, as outdated firmware can cause activation failures.

• Confirm that the carrier has activated the eSIM on your account.

• If all else fails, contact your carrier's customer support for troubleshooting or a replacement eSIM profile.

3. Connectivity issues after activation

Another common issue is the struggle to connect to the network even after the eSIM is activated. In such a situation, the following solutions might help:

• Move to an area with strong signal strength. Poor coverage may cause activation or connectivity delays.

• Go to your device's settings and reset the network configuration to default.

• Check for any pending carrier settings updates on your device.

• For dual-SIM devices, ensure the physical SIM and eSIM do not conflict. Set the eSIM as the primary SIM if needed.

4. Inconsistent performance post-activation

In some cases, the eSIM may activate and connect easily but work sporadically or drop connections frequently. If this happens, try these fixes:

• Turn on airplane mode for a few seconds and then disable it to refresh the network connection.

• Reconfigure settings if a physical SIM is also in use, ensuring the correct priority is set for data and calls.

• Verify with your carrier that your plan supports eSIM functionality fully, including roaming.

Things to know before converting your physical SIM to an eSIM

Although switching from a physical SIM to an eSIM is a simple process, there are a few crucial factors to consider before making the decision. Understanding these points will help prevent potential confusion and challenges.

1. Device compatibility

Not all devices support eSIM technology. Before proceeding, confirm whether your smartphone or tablet is eSIM-compatible. The most common brands supporting eSIM include iPhone XS and later models, Newer Galaxy models, such as the S20 series and beyond, Pixel 3 and newer and certain OnePlus and Huawei models. 

You can also check eSIM compatibility manually by navigating to the Mobile Services or Network & Internet (name may vary by device) in the Settings. For Android users, an alternative method is to dial *#06# and press the call button. If your device is eSIM-compatible, you will see a unique eSIM Identification Number (EID) displayed on your screen.

2. Carrier support

eSIM technology isn't universally supported by all carriers. While major telecom providers in many countries have embraced eSIM, smaller or regional providers may still rely on physical SIM cards. Research your carrier's eSIM policies and verify the following:

• Does your carrier support eSIM in your location?

• Are all carrier services available with eSIM (e.g., roaming, 5G connectivity)?

• Is there an additional cost for eSIM activation?

3. Data backup

Switching to an eSIM may lead to data loss if not handled carefully. Ensure you back up your contacts, messages, and other essential data before starting the conversion. Use cloud services or external storage for a comprehensive backup.

4. Update device software

Before converting your physical SIM to an eSIM, it is crucial to ensure that your device is running the latest software update. Older versions of operating systems may not fully support eSIM functionality, even if the hardware is compatible. 

You can easily update the software by navigating to Software Update or System Updates (depending on your device) under Settings. Tap Check for Updates and install any available updates. Make sure to restart your device after the update to ensure the changes are applied.

5. Troubleshooting preparedness

Be ready to troubleshoot minor issues, as discussed in the above sections, that might arise during or after the conversion process. Familiarise yourself with common problems, such as scanning QR codes or network connectivity issues, and have your carrier's support contact details handy.

6. Potential limitations

eSIMs offer many advantages, but there are some potential drawbacks to consider:

• Limited regional support: In areas where eSIM technology is still emerging, you might experience fewer network options or limited functionality.

• Device locking: Some carriers lock eSIM functionality to their networks, limiting your ability to switch carriers freely.

• Data recovery challenges: If you lose your phone, recovering an eSIM might take longer than replacing a physical SIM card.

Conclusion

Converting your physical SIM to an eSIM is an empowering move that enhances flexibility, supports dual-SIM functionality, and opens up a world of seamless connectivity. However, the process requires careful consideration of factors such as device compatibility, carrier support, and potential limitations. By being well-prepared and informed, you can ensure a hassle-free transition.
