An eSIM isn’t working on your iPhone?

Why is your eSIM not working on your iPhone?

Many reasons can cause your eSIM not to work on your iPhone, and all of them can be a real pain. Just imagine: you're working from abroad and need to send a file, but your connection keeps crashing. To fix it, you have to know what's wrong, right? Knowing the possible issues can help you fix an eSIM failure on an iPhone with just a few taps.

  • Incompatible carrier. Not all mobile carriers support eSIM technology. If your carrier doesn't offer eSIM service, it might be the reason you're struggling to activate it.

  • Network issues. An eSIM requires a strong mobile signal, so it might not work if you're out in the sticks.

  • Outdated software. Your iOS might be too old to guarantee proper eSIM compatibility. Apple often introduces iOS updates to fix eSIM bugs and boost overall functionality.

  • Activation issues. Sometimes, eSIM activation can be tricky if there are multiple steps involved. Closely follow the provider's instructions to activate your mobile data correctly.

  • Device compatibility issues. Older iPhone models may not be compatible with an eSIM. Make sure your iPhone is compatible before you try to purchase an eSIM. 

  • Physical SIM intrusion. A physical SIM card and an eSIM sometimes clash, so having both can be problematic.

  • Carrier problems. Sometimes, everything seems fine with your iPhone, software, or activation, but the eSIM still won't work. Your carrier might be having a bad day. Check with them for service issues.

What to do if an eSIM doesn't work on your iPhone

Whether it's a compatibility issue or a software glitch, you can try a few things to get your eSIM back on track.

1. Check your iPhone’s compatibility

Not all iPhones are eSIM-friendly. Every iPhone before the iPhone XR doesn't support eSIMs. If you have a newer device, you should be able to activate a mobile data plan without hassle. 

If you need help figuring out if your iPhone is eSIM-compatible, check out this list of eSIM-supported devices.

2. Check your carrier’s compatibility

Does your mobile carrier support eSIMs? Some don’t. Call your carrier or check its website to make sure it can provide an eSIM service.

3. Restart your iPhone

If you're struggling to activate your eSIM or your mobile data doesn't work, try turning your phone off and on again. It’s an old trick, but sometimes it works.

  1. Press and hold the volume and power buttons at the same time until the "Slide to power off" slide appears.

  2. Drag the slide and wait for your iPhone to shut down.

  3. Press and hold the power button until the Apple logo appears.

4. Update your iOS

Your iPhone keeps nagging you to update its iOS for a reason. The updates are there to fix bugs, including those related to eSIMs. So keep your iOS up to date.

  1. Go to "Settings."

  2. Tap "General."

  3. Tap "Update now" or choose "Update tonight." 

5. Remove the physical SIM

If your eSIM isn't working, it might need some breathing space. Sometimes, physical SIMs and eSIMs clash. Pop out your physical SIM, restart your iPhone, and give your eSIM another shot. 

6. Check and reset your network settings

To make your eSIM actually do its “esimming,” give your network settings a little nudge. 

  1. Go to "Settings."

  2. Tap "General."

  3. Tap "Reset."

  4. Tap "Reset network settings."

Note that resetting your network settings will delete all saved Wi-Fi passwords.

7. Contact your carrier support

Identifying an eSIM functionality problem by yourself might be tricky. So, if you're still stuck after trying all the above tips, it's time to call the carrier. Reach out to its customer support. The tech team has all the tools to troubleshoot carrier-specific issues.

8. Contact Apple support

If all else fails, contact Apple support or book an appointment at an Apple Store to resolve your eSIM-related issues. The pros will diagnose and fix any hardware or software issues affecting your eSIM.

9. Reinstall and activate your eSIM again

If all else fails, delete and reinstall your eSIM. Maybe a fresh start is all it needs. Here's how to reset an eSIM on an iPhone:

  1. Go to "Settings."

  2. Tap "Mobile service."

  3. Select your eSIM and tap "Delete eSIM."

  4. Then head back to the Saily app.

  5. Tap on your eSIM and hit “Install eSIM.”

The above solution is more of a last resort. It's a bit complicated and can take time, and even after all the effort, it may not work. So we recommend reaching out to Saily customer support — a service representative will be happy to help you with the reinstallation process.
