How to Fix Slow Internet Speeds on Your Travel SIM or eSIM

Staying connected while travelling is essential, especially when you rely on mobile data for maps, translation apps, bookings and keeping in touch with family. Even with a reliable travel SIM or eSIM, there may be times when your internet feels slower than usual. Most issues are simple to fix with a few quick checks.

Here is a practical step by step guide to help you improve your mobile data speed while travelling.

1. Check Your Network Signal

Poor signal strength will always slow down your connection. Your speed may be affected by:

• Thick hotel walls
• Underground stations
• Rural or mountainous areas
• Busy tourist hotspots

Move closer to a window, step outside or restart your phone to reconnect to a stronger tower.

2. Switch to a Different Network (If Your Plan Allows)

Many travel SIMs and eSIMs support multiple local networks. If one network is congested, switching can instantly improve your speed.

To check:

• Open Mobile Network Settings
• Turn off Automatic Network Selection
• Select a different available network

3. Toggle Airplane Mode

Turning Airplane Mode on and off forces your phone to reconnect to nearby towers.

1. Enable Airplane Mode
2. Wait 10 seconds
3. Disable Airplane Mode

4. Restart Your Phone

A restart clears temporary glitches and reconnects you properly to the network, helping fix issues with APN settings, network mode and roaming.

5. Check Your APN Settings

Your travel SIM or eSIM requires the correct APN. Incorrect details often cause slow or unstable speeds.

Confirm that:

• The APN matches your provider instructions
• There are no extra spaces
• Data roaming is enabled

6. Change Your Network Mode

Switching between 5G, 4G and 3G can improve speeds depending on your location.

For example:

• 5G may be available but unstable
• 4G can be stronger and faster in many regions
• 3G may work better in remote or island areas

7. Turn Off Your VPN

VPNs slow down speeds because your data is routed through distant servers. If your connection feels sluggish, try turning off your VPN temporarily.

8. Disable Background Data Usage

Apps may be consuming data without your knowledge. Turn off:

• Automatic updates
• Cloud backups
• Background app refresh
• Auto play on social media

9. Check for Data Limits or Fair Use Policies

Some plans reduce speeds after you reach a daily or total data threshold. Check your usage through your device settings or provider app.

10. Reinstall Your eSIM or Use a Backup SIM

If the problem persists, reinstalling your eSIM or switching briefly to a local SIM can reset your connection and solve lingering issues.

Final Tip

Slow speeds are often caused by location, congestion or minor settings issues. With these quick steps, you can restore your connection and enjoy smoother data throughout your trip.
