When it comes to whether you should delete your eSIM from your old phone, it’s generally advisable to do so, though it’s not always absolutely mandatory. An eSIM essentially holds your cellular profile, which includes your carrier information and activation data. If you leave it on your old device without deleting it, several potential issues could arise.

Firstly, from a security perspective, keeping your eSIM active on a device you no longer use could pose a risk. If the phone falls into the wrong hands, someone could potentially access your cellular service or use the data plan, especially if the phone isn’t locked or protected adequately. Additionally, remnants of personal information tied to your phone number, like carrier-specific settings, could potentially remain accessible.

Secondly, regarding data and settings, an eSIM doesn’t store a lot of personal data, but it does contain your network profile. Leaving it on the old device might not directly impact your existing phone’s functionality, but it can complicate things if you try to reactivate the same eSIM on another device later, depending on your carrier’s policies.

Deleting the eSIM also ensures you start fresh on your new device without any connectivity conflicts. It’s a straightforward process that can prevent future glitches, possible security vulnerabilities, and confusion.

In summary, while not strictly necessary, deleting your eSIM from your old phone is a best practice. It safeguards your personal information, avoids potential service misuse, and keeps your digital footprint tidy as technology evolves. Taking that extra step is a small inconvenience for greater peace of mind.
