Hello, I have an iPhone 11. I need my voicemail to come in after three rings, but it does after 12 -15 rings. Does anyone here know how to customize this?
Voicemail is controlled by call forwarding details. You can set the time (not number of rings) before an unanswered call forwards to voicemail by adjusting the Call Forward Unanswered setting. I think it can be up to 30 seconds. Look up GSM Hash Codes or GSM Service Codes. Can’t be set on WiFi Calling and the last few times I’ve tried it didn’t work for me. YMMV.
