Changing ringtone length

[Emma_S]

I need help changing my ring length from 20 to 30 seconds on my new phone, Samsung A52s.

I have never had an issue before using **61*901*11*30#, but when I do this it says 'Call forwarding when no reply for All Speech Services Connection problem or invalid MMI code'

Can anyone help?

Thanks

Emma

Sorry, I'm a bit of a noob. Tried with 2g only, 3g only, and 2g/3g (auto)  all with data and wifi off, still get error message.

I have the same issue. Has anybody found the answer?
