MMI/NO SERVICES

[Km1]

I used the code *61*901*11*30# after reading post and blogs saying that was the way to lengthen the call time before voicemail kicks in it comes up with an error message invalid MMI code.... only since i cant make or receive calls no dial or anything 😕 how do i reverse it, get my connection back or anything to help occasionally it flashes a forwarding message but i have forwarding setting disabled

The entire network is down currently so it's nothing you did.
To use that code, you first need to disable wifi calling in your MyO2, then after sending the code, you can turn it back on again.

@Km1 There’s a nationwide outage so that’s why you have no connection

You will have to wait till the network is restored. There is a national outage at the moment
