Lengthen ringtime NOT WORKING?

[phonek]

Tried this guide on mine/my partners phones (Air+17 Pro Max), but the amount of rings is still not improving?

"How to Lengthen Ringtime on any O2 Mobile"

https://community.o2.co.uk/t5/How-to-Guides/How-to-Lengthen-Ringtime-on-any-O2-Mobile/bc-p/1812997 

I changed the setting to 60-secs via the website, yet it still stops ringing at just 20-secs/4-rings (timed it!) and goes to Voicemail?

On one iPhone I turned "W-iFI Calling" in Phone settings OFF, and the other iPhone I left that setting ON – both failed to be longer even after waiting two hours for the "Pending" card to change to be the "Active" card in the web settings interface. Both are on latest iOS 26.0.1, as well. 

What am I doing wrong here (this is so overly complicated?!)?

Can't change mine either @phonek  no matter what I set it to or which way I try.

My workaround is to turn off voicemail unless I don't want to take calls.

Does O2 actually know this setting doesn't work? 

(Why have an option for this in Settings –that also offers more than 30 secs, up to 180 secs(!)– when it changes nothing when using it??)

I should think it's beyond O2's technical grasp. 

 Maybe it's something to be offered in the future by but Max 30 seconds seems to be industry standard.

But setting "30-secs" ring doesn't work (forget longer, just that). 

How on earth can this be beyond O2's technical grasp, really, they should make sure it works and if it doesn't then they should know about it, and offer clear info to customers. Has anyone reported this?

It comes up from time to time.  A forum search will bring up the posts

From experience I've found Android phones are the worse.

I switched Wifi and Data off and selected 2G / 3G on a Galaxy S23  handset and the MMI code worked.

Switched everything back after that.

So, December 2025, and NOTHING to do with resetting "How to Lengthen Ringtime on any O2 Mobile" works. No matter what I try, it just ignores me on my iPhone 15 and 16 both. 

Bit of a pain actually.

Yep, as we know, it doesn't work on iPhones.

Tell me about it, I've contacted @Dave-O2 about this issue several times over the last 3 MONTHS(!) trying to get o2 to do something about it, and have gotten precisely one callback from a staffer who didn't understand the issue – despite explaining it to them repeatedly they kept blaming my eSims, instead of seeing the bigger picture that ALL iPhone users have this problem on O2's network! 

See this thread for O2 incompetence:
