More and more people are turning to eSIM technology to simplify their cellular requirements. However, as with all new technologies, eSIM has its own issues and many users have reported problems during or after eSIM installation. In this article, I will provide some of the best solutions to fix eSIM not working on iPhone.

Before moving on to the troubleshooting procedures, I recommend checking out our guide to ensure that you are transitioning to eSIM using the correct method. Depending on the carrier, the eSIM activation procedure on the iPhone may vary, but it usually involves scanning a QR code or entering a unique code provided to you by your carrier.

With the basics taken care of, let’s see how to fix eSIM not working on iPhone.

1. Make sure that the eSIM is activated

If you are having trouble with eSIM on your iPhone, you should first check if your eSIM is activated. If the activation status is negative, you can do the following:

  • Be patient: If you live in a country where eSIMs are allowed and your carrier offers this service, the first thing you need to do is wait for the eSIM to be activated. The time it takes for activation may vary depending on your location and carrier and can range from a few hours to a day or two. You have to wait some time before contacting your carrier to get the estimated activation time.
  • Generate a New QR Code: I recommend that you delay generating a new QR Code for a day or two if your carrier offers and generates an automated action that can be performed using a specific carrier’s app to be scanned for eSIM activation. The updated QR Code will surely make it easier for you to successfully install and activate eSIM on your iPhone.

Resetting network settings can fix network problems on your iPhone. Resetting it will cause the device to forget every Wi-Fi, Bluetooth connection, and VPN settings it has ever used.
