Lyca Mobile eSIM not working: Causes and fixes in 2026

Why is my Lyca Mobile eSIM not working?

A Lyca Mobile eSIM may not work because activation hasn’t completed, the device doesn’t support eSIM technology or is locked to a carrier, mobile data or roaming is disabled, the APN is incorrect, or the plan has expired. If you are new to the technology, understanding what an eSIM is helps make troubleshooting easier.

Common causes include:

• Incomplete activation. Lyca Mobile claims that activation can occasionally take up to 24 hours.

• An eSIM-incompatible or carrier-locked device. Check that your phone appears on a list of eSIM-compatible devices and is carrier unlocked.

• A QR code issue. The QR code may have already been used or may not scan correctly.

• Data settings. Mobile data or data roaming may be switched off.

• An incorrect APN. When APN settings are missing or wrong, your phone shows full signal bars, yet websites and apps won’t load.

• A network or coverage issue. Your phone may not have registered with an available network.

• Outdated software. Older iOS or Android versions can cause setup problems.

• An expired plan or no data allowance. Check that the plan is active and still has data remaining.

If you need another option while troubleshooting, Saily offers prepaid travel data in 200+ destinations, in-app installation, and 24/7 support.

Why is my eSIM on but not working?

If your eSIM is switched on but has no data, check whether it’s selected as your mobile data line, whether data roaming is enabled, and whether its APN is correct.

Remember that installing the eSIM profile, switching the line on, and selecting it for mobile data are separate settings. If another SIM or eSIM remains enabled, your phone may continue using that line for data instead.

Try toggling airplane mode on for about 30 seconds and then turning it off. A full restart can also clear temporary network registration errors.

How to fix a Lyca Mobile eSIM: A step-by-step checklist

Work through these checks in order and test your connection after each one.

1. Restart your phone. This forces the device to reconnect to available networks.

2. Toggle airplane mode on and off. Turn airplane mode on for around 30 seconds, then switch it off.

3. Check the Lyca Mobile line. Make sure the eSIM is enabled and selected for mobile data.

4. Enable data roaming. Confirm that data roaming is switched on for the Lyca Mobile line.

5. Check and re-enter the APN. For Lyca Mobile UK, the current APN is “data.lycamobile.co.uk,” with the username and password left blank. Check local Lyca Mobile instructions if your plan was bought elsewhere.

6. Select the network manually. Turn off automatic network selection and choose an available Lyca Mobile or partner network.

7. Reset network settings. This removes saved Wi-Fi passwords and may reset other network preferences.

8. Update your operating system. Install any available iOS or Android updates.

9. Check your plan. Confirm that it’s active, hasn’t expired, and still has data remaining.

10. Contact Lyca Mobile support. Have your ICCID and EID number ready in case support needs them.

You’ll usually find the main settings in the following locations, though menu names on Android vary by manufacturer:

💡 Good to know: Avoid deleting the eSIM simply to see whether reinstalling fixes it. If you remove your eSIM profile, you’ll likely need to contact your provider for new activation details to set it up again. 

If the problem is specifically an eSIM showing no service on an iPhone, check the line and network settings before removing anything. 

Why is my Lyca Mobile eSIM QR code not working?

A Lyca Mobile eSIM QR code may not work if it’s already been used or expired, your phone isn’t eSIM compatible or is carrier locked, or the device doesn’t have a reliable internet connection during installation.

Lyca Mobile states that its QR code cannot be reused once an eSIM has been removed. If the code won’t scan, try these quick troubleshooting steps:

• Connect to stable Wi-Fi.

• Display the code clearly on another screen.

• Check that the phone supports eSIM technology and is carrier unlocked.

• Try entering the activation details manually.

• Contact Lyca Mobile for a replacement QR code if necessary.

You can learn more about how eSIM QR codes work and why some providers use them during installation.

Saily takes a different approach — you can download the Saily eSIM app, choose a plan, and install it in-app with no QR or activation code to scan or enter manually. 

How do I manually activate an eSIM on Lyca Mobile?

You can manually activate a Lyca Mobile eSIM by entering the SM-DP+ address and activation code from your Lyca Mobile confirmation email instead of scanning the QR code. 

⚒ On an iPhone, go to “Settings” > “Cellular” > “Add eSIM” > “Use QR code” > “Enter details manually.” Enter the SM-DP+ address and activation code provided by Lyca Mobile.

⚒ On an Android device, go to “Settings” > “Network & internet” > “SIMs” > “Add eSIM” > “Enter code manually” to view the available setup options. The wording may vary by manufacturer. 

Keep the phone connected to stable Wi-Fi throughout installation. Once the profile has downloaded, enable the line, select it for mobile data, turn on data roaming when required, and check the APN.

How do I reinstall a Lyca Mobile eSIM?

Reinstalling a Lyca Mobile eSIM usually means removing the existing profile and installing a replacement using new activation details.

Contact Lyca Mobile support before deleting your existing eSIM. Lyca Mobile states that its QR code can’t be reused, so confirm that a replacement profile or code can be issued first.

Once you have the replacement details:

1. Save your account information, such as the phone number and ICCID.

2. Remove the existing eSIM. 

On an iPhone, go to “Settings” > “Cellular” > select the Lyca Mobile line > “Delete eSIM.” 

On an Android device, go to “SIMs,” select the eSIM, and choose “Erase” or “Delete” (wording varies by device).

1. Restart your phone and connect to Wi-Fi.

2. Install the replacement eSIM using the new QR code or activation information.

If you are moving the eSIM to another phone, Lyca Mobile may also need the new device’s EID.

What to do if your Lyca Mobile eSIM still won’t work abroad

If your Lyca Mobile eSIM still has no service after you’ve completed the checklist, a second travel eSIM can keep you online while Lyca Mobile investigates the problem. Many newer phones can store multiple eSIM profiles, and some support two active lines at once.

• Saily has a 4.7 Trustpilot rating and offers prepaid data in 200+ destinations, in-app installation with no QR or activation codes, and 24/7 support. Its built-in eSIM security features include an ad blocker, web protection, and a virtual location feature with 115+ locations. Saily also offers an optional eSIM with a phone number for local calls and SMS.

• Other providers. Holafly, Airalo, Yesim, and eSIM.io also offer travel data plans, while Saily combines connectivity with built-in security tools and app-based setup.

You can also check Saily reviews before choosing a backup provider.

Preparing your eSIM for a trip

Set up and test your travel data before leaving home rather than waiting until you land.

• Check compatibility first. Make sure your phone supports eSIM technology and is carrier unlocked before buying a plan.

• Install your eSIM on reliable Wi-Fi. Download your eSIM at home rather than relying on airport Wi-Fi.

• Screenshot your activation details. Save your activation information, like QR code, ICCID, and APN, so you can access it offline.

• Choose which line does what. If your phone supports dual-SIM functionality, keep your home number for calls and texts and use the travel eSIM for data.

• Check the APN. Incorrect APN settings are a common reason an eSIM has signal but no internet.

• Budget your data. Messaging, browsing, navigation, and translation use far less data than video streaming or large downloads.

• Keep a backup connection. A Saily eSIM can serve as your main or backup data line in 200+ destinations. If your data suddenly cuts out, see why your eSIM might not be working for additional checks.
