Troubleshooting Common eSIM Activation Issues

Switching to a Voyesim eSIM feels futuristic—no more fumbling with tiny SIM cards, no more worrying about losing them mid-travel. With Voyesim, you can activate a plan in minutes and stay connected in over 200+ countries. But like all tech, the activation process isn’t always smooth sailing. If your eSIM is giving you headaches, don’t worry—you’re not alone. Here’s a breakdown of the most common Voyesim eSIM activation issues and how to fix them.

1. Device Compatibility Issues

Not every phone, tablet, or smartwatch is eSIM-ready.

• The Fix: Check your device model against the official eSIM-supported device list. (For example, iPhone XR and newer, Pixel 3 and newer, Samsung Galaxy S20 and above, etc.)

• Pro Tip: Some carriers lock eSIM features, even on compatible devices. Double-check with your carrier.

2. QR Code Not Scanning

You’ve got your QR code, but the camera just won’t cooperate.

• The Fix:

  • Clean your camera lens (yes, smudges matter).

  • Increase screen brightness if scanning from another device.

  • If it still doesn’t work, enter the activation details manually (SM-DP+ address, activation code).

3. Activation Failed or Stuck

Sometimes the process freezes or displays “Activation Failed.”

• The Fix:

  • Restart your device.

  • Make sure you’re connected to a stable Wi-Fi network (mobile data won’t cut it).

  • Delete the eSIM profile and re-add it.

4. No Signal After Activation

You’ve activated successfully, but your phone stubbornly refuses to connect to the network.

• The Fix:

  • Double-check your carrier’s coverage in your region.

  • Toggle Airplane Mode on/off.

  • Go into Settings > Mobile Networks and manually select your carrier.

5. Data Not Working

Calls may work, but the internet is nowhere to be found.

• The Fix:

  • Ensure Mobile Data is enabled for the eSIM profile.

  • Check your APN (Access Point Name) settings—sometimes you need to enter them manually.

  • Reset Network Settings if all else fails.

6. eSIM Profile Deleted by Mistake

Deleted your eSIM while clearing settings? Oops.

• The Fix:

  • Contact your carrier or eSIM provider for a reissue. Most will send you a fresh QR code instantly.

7. Travel-Related Issues

You’ve landed abroad, but your eSIM refuses to play nice.

• The Fix:

  • Make sure your plan includes roaming in that region.

  • Check if your device is set to the right network band.

  • Restart your device once you land (airplane mode trick helps too).

8. Carrier Restrictions

Some carriers limit eSIM use for prepaid or specific plans.

• The Fix:

  • Ask your provider if eSIM is supported for your plan type.

  • If not, consider switching providers (especially if you travel frequently).
