Does Fido support call barring?
It keeps ask for a 4 digi password. Chatted they said is Samsung problem but the password should obtain by the provider.
My Rogers phone works fine with call barring without password.
You should indeed be able to use the feature on your device.
Can you tell me if your phone is a Fido phone or unlocked one?
Also, would it be possible for you to test your SIM card in a different Android device to see if you're still being asked for a password?
Finally, do you have your own password that you have set up on your SIM?
Let me know and we'll take it from there.
