Common Mistakes to Avoid

1. Not Checking Device Compatibility

Many travelers overlook verifying whether their smartphone supports eSIM technology.

How to Avoid:

• Ensure your device is eSIM-compatible before purchasing an eSIM plan.
• Popular compatible models include:
  • Apple: iPhone XS and newer.
  • Samsung: Galaxy S20 series and newer.
  • Google Pixel: Pixel 4 and newer.

2. Choosing the Wrong eSIM Plan

Selecting a plan that doesn’t match your destination or data needs can cause issues.

How to Avoid:

• Confirm that the eSIM plan covers your destination.
• Assess your data needs:
  • Light Usage: Emails and messaging (1–3GB).
  • Moderate Usage: Social media and browsing (5–10GB).
  • Heavy Usage: Streaming and video calls (10GB+).

3. Not Activating the eSIM Before Traveling

Many travelers assume they can activate their eSIM after reaching their destination, only to face challenges like no Wi-Fi or poor signal.

How to Avoid:

• Activate your eSIM while connected to Wi-Fi before departing.
• Test the eSIM to ensure it connects to a network.

4. Failing to Set the eSIM as the Primary Data Line

Forgetting to configure the eSIM as the default data line can result in your physical SIM incurring roaming charges.

How to Avoid:

• Set the eSIM as the primary data line in your phone settings:
  • iPhone: Settings > Cellular > Cellular Data > Select eSIM.
  • Android: Settings > Mobile Network > Preferred SIM for Data > Select eSIM.

5. Ignoring Network Preferences

Incorrect network settings can lead to connectivity problems or slow speeds.

How to Avoid:

• Enable roaming if your eSIM plan requires it.
• Choose the appropriate network type (4G or 5G) based on your device and plan.

6. Overlooking Data Usage Limits

Failing to monitor data consumption can lead to unexpected overages.

How to Avoid:

• Use your device settings or the eSIM provider’s app to track data usage.
• Disable background app refresh and auto-updates to conserve data.

7. Not Saving eSIM Details

Misplacing your eSIM QR code or activation details can make reinstallation difficult.

How to Avoid:

• Save a digital or printed copy of your eSIM activation details for future use.

Additional Tips for a Successful eSIM Configuration

1. Download Offline Resources

• Save maps, travel guides, and other essential apps offline to minimize initial data usage.

1. Use Wi-Fi Whenever Possible

• Connect to free Wi-Fi in hotels, cafes, and public spaces for data-heavy tasks like uploads or downloads.

1. Check Local Network Compatibility

• Verify that your eSIM provider partners with reliable carriers in your destination.

1. Keep a Backup SIM Card

• Carry a physical SIM card or portable Wi-Fi hotspot as a fallback option.
