What happens when your Smart SIM isn't working? ℹ️
If your Honest Smart SIM isn’t connecting properly, your device might not access the supported apps as expected. This can happen if settings like data roaming, VPNs, or Private DNS aren’t configured correctly. By checking and adjusting these settings, you'll get your Smart SIM back up and running.

Test Your Smart SIM in the Honest app 🔄
Once your device is set up, check your Smart SIM connection using the Smart SIM test in the Honest app. It only takes a few seconds and will confirm if your Smart SIM is working as it should.
If you see an error or connection issue
Please double-check that you’ve followed all the device setup steps:
Data roaming is turned on
VPNs are disabled
All other connections (WiFi, other SIMs) are off
You’re using the supported apps
Then restart your device and try the test again.
Reactivating a Removed Smart SIM 🔄
If your Smart SIM has been removed, you can reinstall it using the QR code in your initial Honest Mobile setup email. If you no longer have the QR code, request a replacement from the team.
Remember, your Smart SIM remains active until it is explicitly canceled. If issues persist, consider requesting a replacement Smart SIM or deleting and reinstalling the current eSIM from your settings.
