Why are my calls or SMS not going through?

Common causes #

• Your line is not fully activated yet.
• You do not have enough airtime or an active voice/SMS bundle.
• Your device signal is weak.
• The phone is set to the wrong SIM for calls or SMS.
• The number dialled is incorrect or blocked.

What to try #

1. Restart the device.
2. Check balances in the app or USSD flow.
3. Test with a different number.
4. Check whether data is working too.
5. Confirm that your SIM is inserted and detected correctly.

If everything fails #

Contact support and tell them whether calls, SMS, and data are all affected or only one service. That helps narrow things down quickly.
