Has this ever happened to you? You excitedly take your shiny new iPhone out of the box, ready to set it up with an eSIM, only to be confronted with an error message: “Unable to activate eSIM.” Deflated, you wonder what went wrong and how you can resolve the issue.
Unfortunately, this is an all too common problem encountered by many iPhone users, especially those with the iPhone 14 series or running iOS 16. But don’t despair! In this guide, we’ll walk you through some simple troubleshooting steps to get your eSIM activated and your iPhone up and running in no time.

But first, what exactly is an eSIM?
An eSIM, short for embedded SIM, is a digital SIM that allows you to activate a cellular plan from your carrier without having to use a physical nano-SIM card. It’s a convenient, easy way to get cellular service, especially for frequent travelers who need service in multiple countries. Many of the latest iPhone models, including the entire iPhone 14 lineup, support eSIM.
While the promise of eSIM technology is exciting – no more fiddling with trays and tiny SIM cards – the reality is that the activation process doesn’t always go smoothly. A number of factors can cause errors when trying to activate an eSIM, leading to frustration for users eager to start using their new iPhone.
Some common reasons you may see an “Unable to activate eSIM” error on your iPhone include:
- Your eSIM is already activated on another device
- You have poor cellular reception
- There’s an issue with your iPhone’s cellular settings
- Your carrier doesn’t support eSIM or is experiencing technical difficulties
The good news is that for most of these issues, there are straightforward steps you can take to resolve the problem yourself, without having to contact your carrier or visit an Apple Store.
Step 1: Make Sure Your eSIM Isn’t Being Used on Another Device
One of the most frequent reasons for an eSIM activation failure is because that eSIM is already actively being used on another device. Unlike a physical SIM card which you physically move from one device to another, your eSIM can only be active on one device at a time.
So if you’re trying to activate an eSIM on a new iPhone, but you’re still using that same eSIM on your previous iPhone or Android phone, you’ll need to deactivate it first on your old device before activating it on the new one.
Here’s how to deactivate the eSIM on your old iPhone:
- Open the Settings app
- Tap Cellular
- Tap the plan you want to remove
- Tap Remove Cellular Plan
- Tap Remove to confirm
And here’s how to delete an eSIM on an Android device:
- Go to Settings
- Tap Network & Internet
- Tap Mobile network
- Tap the eSIM you want to delete
- Tap Delete
Once you’ve successfully deactivated your eSIM from the old device, try activating it again on your new iPhone. Hopefully you’ll be up and running! But if you still get an error message, don’t throw in the towel just yet – there are a few more things to try.
Step 2: Check Your Cellular Reception
This may seem really basic, but one easily overlooked reason for an eSIM activation failure is poor cellular reception. If your iPhone isn’t getting a strong enough signal from the cell tower, it won’t be able to complete the eSIM activation process.
Some things that could cause reception issues include:
- You’re in an area with limited cellular coverage
- You’re inside a building with thick walls that block the signal
- There’s interference from other electronic devices
- There’s an issue with your carrier’s network
To see if poor reception is the culprit, try activating your eSIM again, but this time do it while outside or near a window with clear line of sight to the sky. If the activation is successful, you’ll know that signal strength was likely the issue.
If you’re still having trouble, check for any temporary network outages in your area by visiting your carrier’s website or social media. Carriers usually post updates if they’re experiencing issues. You may just need to wait it out until the network problems are resolved.
Step 3: Reset Your iPhone’s Network Settings
If your eSIM still won’t activate after confirming it’s not tied to another device and ruling out reception issues, the next step is to reset your iPhone’s network settings. This will erase all saved Wi-Fi networks and passwords, cellular settings, and VPN and APN settings.
Don’t worry – it won’t delete any of your other data like photos, apps, or documents. It just clears the slate to give you a fresh start on network connectivity.
Here’s how to reset network settings on your iPhone:
- Open the Settings app
- Tap General
- Scroll down and tap Transfer or Reset iPhone
- Tap Reset
- Tap Reset Network Settings
- Enter your passcode if prompted
- Tap Reset Network Settings to confirm
Your iPhone will restart. Once it powers back on, try activating your eSIM again. If it works, great! If not, there’s one more step to try.
Step 4: Contact Your Carrier
If you’ve tried all the troubleshooting steps above and still can’t get your eSIM to activate, your last resort is to contact your carrier’s customer support. There could be an issue on your carrier’s end that’s preventing the activation from completing.
When you call, be sure to tell the support representative that you’ve already tried the following:
- Made sure the eSIM isn’t still active on another device
- Checked that you have good cellular reception
- Reset your iPhone’s network settings
This information will help them investigate further to identify the underlying cause of the problem. They may be able to activate the eSIM on their end, send you a new eSIM activation code, or escalate the issue to a specialist team for resolution.
Some carriers also offer support through online chat or social media, so those are also options if you don’t want to call in.
The Bottom Line
Activating an eSIM on your iPhone should be a simple, seamless process, but sometimes you may hit a snag and see an “Unable to activate eSIM” error message. While it’s frustrating, most of the time you can resolve the issue yourself by following these steps:
- Check that your eSIM isn’t still active on another device. If it is, deactivate it and try again.
- Make sure you have good cellular reception. Go outside or near a window and see if the activation completes.
- Reset your iPhone’s network settings by going to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- If the above steps don’t work, contact your carrier’s customer support for further assistance. They may need to provision your eSIM on their end.
In most cases, one of these steps should do the trick and you’ll have your eSIM activated in no time. While the process may not feel as effortless as popping in a physical SIM card, the convenience of an eSIM is worth putting up with the occasional activation issue. Just keep this guide handy in case you need to troubleshoot in the future!
