[AC Question]

I want to know how to adjust the number of rings on my Samsung A3 2016.
*#61*11# just returns info but no number

Voicemail is a carrier-based service, you will need assistance from your carrier support team to adjust this. You might also be able to find help online, I'd help you with the search but you don't tell us what carrier you're with.
