Hi ​@Ududbfhd8ejr 

I’m sorry to hear this, have you tried dialing the following?

61*12330#

This should make the ringing as long as it can be adjusted to at 30 seconds.

Hi, I just tried this as getting same problem and it shows USSD code running then connection problem or invalid MMI code. My phone status shows 4 bars, WiFi connected with 4arcs and 2 arrows and WiFi calling.

Hey there ​@Corrin, sorry to hear that.

What phone do you have and what’s your full postcode?

Have you always had this issue with us, or more recently?

Is it only calls from businesses/landlines etc that you’re missing, or normal mobile numbers too?

Thanks,

Tyler

Hi, my phone is Samsung A34 5g. My postcode is WD18 7SA. It started in November, I only noticed it from landlines then as don't get many calls. Yesterday I was waiting for an important call and it went straight to voicemail this could have been from a mobile, landlines or business phone.

Hey there ​@Corrin, sorry to hear that.

Have you tried disabling, and then re-enabling voicemail via the iD Mobile app/website?

Do you have call forwarding enabled?

Thanks,

Tyler

Yes, I have call forwarding but I cannot disable it when unreachable

Apologies, just to understand, what happens when you attempt to remove the call forwarding?
