You generally only need to delete the eSIM when erasing an iPhone if you are not going to use that number/plan on that device anymore, such as when selling, trading in, or giving away the phone. If you are just resetting the phone to fix issues or starting fresh but will keep using the same number and carrier on the same device, you should usually keep the eSIM when erasing.

Quick Scoop: What “Delete eSIM” Really Means

  • The eSIM is your digital SIM card that stores your mobile plan and phone number from your carrier.
  • When you erase an iPhone (Erase All Content and Settings), iOS asks whether to:
    • Keep eSIM and erase data – wipes your personal data but keeps the mobile plan on the phone.
* **Delete eSIMs and erase data** – wipes data and removes the stored mobile plans from the device.

Deleting the eSIM removes the plan profile from the phone, but it does not automatically cancel your carrier subscription – that still has to be done with the carrier if you’re ending service.

When You Should Keep the eSIM

Keep the eSIM when erasing your iPhone if:

  1. You’re keeping the phone yourself
    • You just want a fresh start, to clear data, or to fix software issues, but you’re staying with the same phone number and carrier.
 * Choosing “Keep eSIM and erase data” lets you set the phone up again and still have service working immediately after.
  1. You’ll reuse the same plan on this device
    • Reinstalling a deleted eSIM sometimes requires going through carrier activation again, which can be slower or more confusing depending on the provider.
 * Keeping it avoids needing QR codes, carrier apps, or support calls in most cases.

In most everyday scenarios where you’re not changing phones or carriers, keeping the eSIM is the simpler, safer choice.

When You Should Delete the eSIM

Delete the eSIM when erasing your iPhone if:

  1. You’re selling, trading in, or giving away the iPhone
    • You don’t want your phone number or carrier plan staying tied to a device that someone else will own.
 * Use “Delete eSIMs and erase data” so the new owner gets a clean phone with no trace of your service.
  1. You’re permanently done with that plan or carrier on this device
    • You switched carriers and no longer need the old eSIM profile on the phone.
    • You’re moving the number to another phone and don’t want the old device to stay associated with that line.
  2. Your carrier told you to remove/re-add the eSIM to fix problems
    • Some network issues are solved by deleting the eSIM and re-downloading it from the carrier.

If you delete an eSIM you meant to keep, you’ll usually need to reactivate it via your carrier’s website, app, QR code, or support line.

Practical Scenarios (What To Tap)

Here are some common “what should I do?” situations:

  • “I’m keeping my iPhone, just want a full reset.”

    • Result: No personal data and no mobile plan left on the device for the next owner.
