eSIM not working on iPhone? 13 Ways fix it!

More people are turning to eSIM technology to streamline their cellular requirements. However, as with all new technologies, eSIMs have their share of problems, with many users reporting problems during or after eSIM installation. In this article, I’ll provide some of the best solutions to fix eSIM not working on iPhone.

Before moving on to the troubleshooting procedures, I’d recommend going through our guide to ensure you have switched to an eSIM using the right approach. Depending on the carrier, the procedure for activating an eSIM on an iPhone can vary, but it typically entails scanning a QR code or entering a unique code given to you by the carrier.

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

1. Ensure that eSIM is activated

If you are experiencing problems with the eSim on your iPhone, you should first check whether your eSIM has been activated. If the activation status is negative, you may do the following:

  • Keep patience: Assuming that you’re residing in a country where eSIMs are permitted and your carrier offers this service, the first thing to do is to wait for the eSIM to become active. The time it takes for activation can vary depending on your location and carrier, which can range between a few hours to a day or two. You should wait for some time before reaching out to your carrier to ask for an estimated activation time.
  • Generate a new QR code: I recommend you hold off on creating a new QR code for a day or two if your carrier offers an automated procedure that can be carried out by using a specific carrier app and generates one to scan for the activation of the eSIM. An updated QR code will undoubtedly make it easier for you to install and activate your eSIM on your iPhone successfully.

2. Reset Network Settings on iPhone

Resetting the network settings can be a solution to the network issues on your iPhone. Resetting it will make the device forget every Wi-Fi network, Bluetooth connection, and VPN setting it has ever used.

  1. Launch Settings.
  2. Select General → Choose Transfer or Reset iPhone.

    Select General and choose Transfer or Reset iPhone

    On iPhones with a Home Button, you’ll need to swipe up.

Connecting to a VPN service can improve your device’s functionality while also enhancing your online security and privacy. However, using VPN with an eSIM can also cause some issues. In some circumstances, the VPN may stop your iPhone from successfully connecting to the cellular network or gaining access to the eSIM.

You might be able to fix this problem by turning off your VPN and trying to set up your eSIM once more.

  1. Head to the Settings app → Go to General
  2. Scroll down and select VPN & Device Management → Toggle off VPN.

Note: It is recommended that you refer to the official article provided by your VPN provider to disable any third-party VPN applications you may have installed on your iPhone.

6. Turn on Data Roaming

  1. Navigate to Settings → Go to General.
  2. Tap Cellular/Mobile Data Options.
  3. Toggle on Data Roaming.

    Select Cellular Data and choose Mobile Data Options

13. Switch to a physical SIM

While eSIMs have numerous benefits over traditional SIM cards, such as the ability to store multiple phone numbers and activate a new phone plan without a physical card, they can also be more complex to set up and are susceptible to technical issues.

Switching to a physical SIM card may be a permanent solution to any problems you are experiencing with your eSIM.

However, it is important to ensure that your phone is compatible with a physical SIM card by consulting your carrier. It’s worth noting that the latest iPhone 14 models sold in the USA no longer support physical SIM cards.

Moreover, it’s essential to have the correct type of SIM for your device.
