Error code with Call Diverts on Android

[koala321]

Hello, I have an Android 14 smartphone, and recently was sent a new replacement SIM card from O2.

However, when I go into the Phone app, tap Settings, Calling accounts, and Call Forwarding it shows a message box that says 'Call Settings error Network or SIM card error' and the Call Diverts are switched off and grayed out. When I go into 'additional settings' Caller ID is also greyed out. Because of this I can't alter the length of time the phone rings for Voicemail to 30 seconds - when I type in the code **61*901*11*30# to change the length I get the same message.

I rang O2 Customer Services but they said there was nothing wrong with the SIM card and I needed to take my phone to an O2 shop. It's a new HMD Pulse, I only bought it last November.

@MI5 in previous threads on the same subject suggested that WiFi calling needs to be switched off. How do I do that? If I call Customer Services will they switch it off for me? Is that the reason I have this problem?

If so, should I ring them back and ask them to switch off WiFi calling?

These things are sent to try us! 😄

Call forwarding isn't supported on PAYG so the MMI codes wont work, nor is WiFi Calling on o2, so there is nothing for Customer Services to turn off..

If you are simply wanting to lengthen the number of rings before calls go to voicemail then see a post in this thread on how to do it via MyO2

I'm going round in circles with this.

@madasaf1sh I'm talking about Call Divert for Voicemail. Call Divert usually works on PAYG phones.

@Enlli I am trying to length the length but the code your guide says to lengthen to 30 seconds (which normally works) brings up the message 'Call Settings error' rather than actually changing the length.

As I pointed out it can be done via My O2

If you want to try the codes then. Turn Off WiFi. Go into Network Type and set it to 2G if you can. If not then 2G 3G.

I've done that for people and it seems to work

That advice is only relevant to contracts @koala321 

Additionally, on contracts, voicemail divert settings can be set in your MyO2, but not sure if it's the same for PAYG.
