You cannot change the number of rings on iPhone through any iPhone setting, because the carrier controls how long your phone rings before sending a call to voicemail. The only documented way to adjust this unanswered-call timeout is a carrier-side forwarding code, not an iPhone menu.
Can you change the number of rings on iPhone?
There is no documented path in iPhone Settings, Phone app settings, or per-contact settings for changing ring duration before voicemail. Apple support discussions confirm that the carrier controls the unanswered-call timeout, and Apple does not provide an iPhone setting for it. The only workaround is a carrier forwarding code entered in the Phone app keypad.
The only working method: carrier forwarding codes
This method uses a conditional call forwarding code that tells your carrier how many seconds to wait before routing an unanswered call to voicemail. Follow these steps:
- Open the Phone app and tap Keypad.
- Dial *#61# and tap Call to view your current voicemail forwarding number.
- Record the number shown after "Forwarding to +", this is your voicemail forwarding number.
- Dial 61+[forwarding number]11[seconds]# and tap Call. Replace [seconds] with a value from 5 to 30 seconds, in 5-second increments (for example, 30 seconds: 61+[number]*11*30#).
- Place a test call to verify the new ring duration.
No restart is required after dialing the code; the change takes effect immediately. Some carriers also support the 3001#12345# Field Test mode method, which can surface carrier codes for adjusting ring time.
What about Live Voicemail?
Live Voicemail, found under Settings > Apps > Phone > Live Voicemail, can intercept calls before the carrier timeout completes. If you want the carrier forwarding code to work as expected, you may need to turn off Live Voicemail in that same setting. Live Voicemail is not the same as a user-set ring count, but it can change when the call is handled.
Contact your carrier if the code doesn't work
Some carriers do not support changing the delay through forwarding codes. If the code fails, only your carrier's support team can confirm or adjust the ring duration, because the timeout is carrier-controlled. Apple discussion posts consistently state that the carrier is the party that can change the ring duration before voicemail.
Frequently Asked Questions
Can I set different ring durations per contact?
No documented iPhone feature exists for setting different ring durations per contact. The available information describes ring duration as a carrier-level timeout, not a contact-specific iPhone setting. If you are experiencing ringer and ringtone issues with specific contacts, those are unrelated to the carrier timeout. You can use third-party apps to achieve different ring durations for different contacts.
Do I need to restart after changing the number of rings?
No restart is required. The documented process is to dial the code and then place a test call to confirm the change.
Will changing the number of rings affect my voicemail settings?
Changing the ring duration affects when calls route to voicemail (the "when unanswered" forwarding), but it does not change your voicemail mailbox settings themselves. You may need to turn off Live Voicemail separately if you want the carrier timeout behavior to apply as expected. The default number of rings on an iPhone is typically set to 20 seconds.
