eSIM Not Working in Italy? (2026 Troubleshooting Guide)

If your Italy eSIM is not working, there are several common reasons why mobile internet may not connect properly.

Most issues are related to data roaming settings, APN configuration, network selection, installation steps, or temporary network refresh problems.

Quick answer: In many cases, Italy eSIM issues can be fixed by enabling data roaming, selecting the eSIM for mobile data, restarting the phone, or checking the APN settings.

Common Italy eSIM Problems

Travelers in Italy most commonly report:

• No internet connection
• eSIM connected but no data
• Slow mobile internet
• No network signal
• eSIM not activating
• Roaming not working
• Apps not loading

1. Make Sure Data Roaming Is Enabled

Most travel eSIM plans require data roaming to be enabled.

If data roaming is disabled, the eSIM may connect to a network but mobile internet may not work.

How to check:

• Open mobile network settings
• Select your Italy eSIM
• Enable Data Roaming

2. Make Sure the eSIM Is Selected for Mobile Data

Some phones continue using the primary SIM card for mobile data even after installing the eSIM.

Check that the Italy eSIM is selected as:

• Preferred mobile data line
• Active data source

3. Restart Your Phone

Sometimes the phone needs a quick network refresh after arriving in Italy.

Restarting the device can help the eSIM reconnect properly to the local network.

4. Try Airplane Mode for 30 Seconds

A quick airplane mode reset may help refresh the mobile network connection.

Steps:

1. Enable Airplane Mode
2. Wait 30 seconds
3. Disable Airplane Mode
4. Wait for network reconnection

5. Check the APN Settings

If internet still does not work, the APN may need to be entered manually.

For NoveSIM eSIM, use:

Setting	Value
APN	data.esim

In many cases, APN settings configure automatically.

6. Disable Automatic Network Switching

Some devices may continuously switch between networks, which can interrupt connectivity.

Try manually selecting a local supported network.

How to check:

• Open Mobile Networks
• Select your eSIM
• Disable automatic network selection
• Choose an available supported network manually

7. Make Sure Your Phone Supports eSIM

Not all devices support eSIM functionality.

Your phone must:

• Support eSIM
• Be carrier unlocked

Check compatible eSIM devices

8. Check If the eSIM Was Installed Correctly

If installation was interrupted, the eSIM profile may not activate properly.

Most travelers install the eSIM using:

9. Coverage Can Vary Across Italy

Coverage is usually strongest in cities, airports, tourist areas, and populated coastal towns.

Signal quality may vary in:

• Tunnels
• Mountain regions
• Remote beaches
• Ferry routes

10. Slow Internet in Italy

If your eSIM works but internet is slow, possible reasons include:

Moving outdoors or restarting the connection may help improve speed.
