I am not getting alerts for voicemail. The only way I can access voicemail to restart my phone. When I go into the call settings and try to enable the Always forward function using the default code: VM: 555, I get Failed to read data - unexpected response from network, as a response. Can you provide a solution for this problem?
As Plusnet mobile is an MVNO, we do have a basic voicemail service which may not always have the same functionality as other mobile networks. We tend to find that the voicemail notifications do vary from handset to handset, some handsets do allow you to manually enable the notifications, but this is not something we can do via the network.
I'm sorry for any inconvenience this may have caused, if you've any questions please feel free to send myself a PM - I'm happy to help.
