How to Reset an eSIM on iPhone: Step-by-Step Fix for Travel Connectivity [2025]

If your iPhone suddenly loses signal while using an eSIM, you're not alone. Whether you're traveling abroad or just running errands across town, eSIM connectivity issues can disrupt access to essential tools like maps, messages, and mobile data. iPhones are built to handle eSIM technology well, but occasional hiccups — especially after switching plans, software updates, or traveling across networks — can require a manual reset.

Resetting your eSIM might sound like a big step, but sometimes it's the fastest fix when nothing else seems to work. Knowing how to reset it gives you one more way to stay in control. If you're using a provider like Nomad, resetting your eSIM can quickly restore service and get you back online with minimal hassle. Let’s look at why these issues happen and what signs tell you it’s time to reset your eSIM.

Common iPhone eSIM Issues – And When to Reset

Running into problems with an eSIM on your iPhone doesn’t always mean there’s a major problem. Just like with any digital service, glitches can pop up occasionally, especially after iOS updates, changing carriers, or installing a new plan while traveling. Here are some common signs your eSIM isn’t working correctly:

• No signal or sudden loss of connection, even in areas with good coverage
• Cellular data not working, or apps refusing to connect when off Wi-Fi
• Carrier name not appearing in the settings
• Trouble toggling between eSIMs or after using Airplane Mode
• eSIM stuck on “Activating” after setup
• Mobile network-related features like SMS or data working slowly
• eSIM not registering even after inputting details or scanning a QR code

Often, swapping to a new travel eSIM without removing an older profile can confuse your iPhone. If restarting, toggling mobile data, or checking usage limits doesn’t solve the issue, a reset might be necessary.

What to Do Before You Reset Your eSIM on iPhone

Before you jump into resetting your eSIM, taking a few precautionary steps can help avoid setup issues, data loss, or incomplete activation — especially when you're relying on mobile data while traveling.

Preparing Your iPhone for an eSIM Reset

1. Back up your iPhone: Use iCloud or Finder on a Mac to make a full backup of your device. This saves settings, messages, and app data in case something unexpected happens.

2. Save Your eSIM Details: Note down your eSIM activation info — this might include the QR code, manual entry details, or carrier app credentials. If you're using a provider like Nomad, check the app for options to retrieve or resend your plan.

3. Review your Current Cellular Settings: Go to Settings > Cellular (or Mobile Data) and confirm which eSIM line is active. If the line appears inactive or missing, a reset may help resolve the issue.

4. Connect To a Stable Wi-Fi Network: After removing your eSIM, you’ll need an internet connection to reactivate it. Be near a stable Wi-Fi network so your phone doesn’t get stuck mid-process.

With these steps done beforehand, you're ready to reset your iPhone’s eSIM and restore full mobile service with minimal disruptions.

What to Do If Your eSIM Still Isn’t Working After a Reset

Even if you’ve followed all the steps for a successful reset, there’s still a chance something won’t work quite right. That’s okay. Some final troubleshooting steps can often push things over the finish line.

Here are a few things to try if your eSIM still isn’t working right:

• Check for iOS software updates If your iPhone is running older system software, it might stop new eSIMs from working. Go to Settings > General > Software Update and install any available updates. .

• Double-check Wi-Fi Activation usually depends on a solid Wi-Fi connection. If your phone is connected to weak or public networks, switch to a private and stronger connection.

• Review all eSIM info entered If you typed in activation details instead of scanning a code, review every field. Small errors like a wrong digit or missing space could block activation.

• Reset network settings This won’t delete anything important, only saved Wi-Fi networks, Bluetooth info, and other network-related preferences. Tap Settings > General > Transfer or Reset iPhone, and choose Reset Network Settings.

• Switch Airplane Mode on and off Enable Airplane Mode for about 10 seconds, then turn it off. This forces the phone to re-search for any available connections and sometimes re-establish your eSIM connection.

Frequently Asked Questions (FAQs)

Will resetting my eSIM delete my data or phone number?

No, resetting your eSIM only removes the digital SIM profile from your device. It does not affect your Apple ID, stored data, or your mobile number—though you’ll need to reactivate the eSIM to restore service.

Can I reinstall the same eSIM after removing it?

In many cases, yes—but it depends on your eSIM provider. Providers like Nomad allow you to access your eSIM details again via the app or email. Some carriers may limit how many times you can reinstall a profile.

Do I need to reset my eSIM after every trip?

Not necessarily, resetting is only needed if you're facing connectivity issues or switching providers. Your eSIM can remain installed for future travel, especially if your phone supports multiple profiles.

What’s the difference between removing and turning off an eSIM?

Turning off disables the eSIM temporarily (you can turn it back on any time). Removing it deletes the profile, and you'll need to reactivate it. If you're unsure, it's better to toggle it off rather than delete it.

How do I avoid losing my eSIM while traveling?

Back up your activation details or use a provider that stores them in-app, like Nomad. Always install your eSIM before your trip when you have Wi-Fi access.
