Ask HN: Why is it impossible to increase iPhone rings before vmail forward?

Not joking. My mother has an iPhone and it rings maybe 3 times then goes to vmail. She can't get it out of her purse fast enough. I thought no problem to increase rings before that. No settings, no options at all. AT&T makes no mention of it on their support site other then to have a support rep do it. I had three different reps (adv tech) swear to me on three different calls that did it for her and all failed. They have a setting that allows up to 40secs before forwarding they can configure I suppose. Each of them did not work. I did various #61 carrier programming ideas around the Internet but it's insane this is impossible.

Great thread that illustrates the mess. Some AI generated steps that are nonsense (there are no settings as mentioned) then everyone mentioning contacting the carrier.
