❓ eSIM Troubleshooting FAQs

Why is my eSIM showing "No Service"?

Most common reasons: 1) Data Roaming is OFF (turn it ON), 2) eSIM not activated yet (wait 2 minutes after scanning QR), 3) Poor coverage area (move to different location), 4) Plan expired or out of data.

Can I reinstall eSIM if I delete it?

It depends on your provider. BNESIM eSIMs can be reinstalled using the same QR code. Some other providers issue one-time-use QR codes that can't be reused. Check with your provider before deleting.

How long does eSIM activation take?

Typically 30 seconds to 2 minutes. If it takes longer than 5 minutes, try restarting your device and rescanning the QR code.

Will resetting network settings delete my eSIM?

No - resetting network settings will NOT delete your eSIM. It only resets WiFi passwords, VPN settings, and network preferences. Your eSIM profile stays installed.

Why does my eSIM work in one city but not another?

Different carriers have different coverage areas. Try manually selecting a different network: Settings → Cellular → Network Selection → Manual → Choose another carrier from the list.
