Switch off voicemail for security gate sim

[Mattsellors1]

I have a SIM card in my security gate. The number did not have voicemail but that seems to have been switched on. This causes an issue with the operation of the gates. I need a way to switch off voicemail which doesn't involve sending texts from the sim number of phoning from it as the sim is locked in the gate control unit.

Hi @Mattsellors1  you can't turn off voicemail but can stop people leaving messages if that will work. 

Voicemail can’t be switched off completely. But, to stop people leaving you voicemail messages, turn message recording mode off.

On your phone:

1. Dial 759.
2. Press 3.
3. Press 5.
4. Press 1.

Hi John. Thanks but this wont work for me as I cannot dial from the gate control unit.

I suspect the only solution will be to remove the SIM from the gate...  (Unless Sky can do this remotely but you'd have to call them)
