Many iPhone 15 users want to customize how long their phone rings before a call goes to voicemail. By default, the iPhone rings for a preset number of times, but sometimes you need to extend or shorten this duration. This article solves the problem of adjusting the ring duration so you never miss important calls or get voicemail too quickly.
The iPhone 15 itself does not have a direct setting to change the number of rings. Instead, you adjust the ring duration by modifying the voicemail delay through your carrier using special dial codes. This guide explains how to do that, why it works, and offers troubleshooting and best practices to ensure your calls ring exactly as you want.
How do you change the number of rings on iPhone 15?
You cannot directly change the number of rings on the iPhone 15 itself. Instead, you adjust the ring duration by changing the voicemail delay time through your mobile carrier using dial codes. This controls how long your phone rings before diverting calls to voicemail.
The iPhone 15 does not include a built-in setting to change the number of rings. The ring duration depends on your carrier’s voicemail system. By dialing a specific code with your phone number and desired ring time, you tell the carrier how long to wait before forwarding to voicemail. This delay is measured in seconds, and each ring typically lasts about 6 seconds. For example, setting a 30-second delay results in approximately 5 rings before voicemail picks up.
To change the number of rings, you use a GSM code format: **61*voicemailnumber**11*seconds#. This code sets the delay for unanswered calls. The voicemail number is your carrier’s voicemail access number, and the seconds value is the delay before voicemail answers. You can find your voicemail number by checking your carrier’s support or by dialing *#61# on your iPhone 15.
After dialing the code and pressing call, the carrier updates your voicemail delay setting. This method works for most GSM carriers worldwide, including AT&T, T-Mobile, and Verizon. However, some carriers may use different codes or not support changing ring duration.
What prerequisites are required for changing the number of rings on iPhone 15?
- Carrier support for voicemail delay codes: Your mobile carrier must support GSM dial codes to change voicemail delay times for this method to work.
- Access to voicemail number: You need to know your carrier’s voicemail access number to include in the dial code.
- Basic knowledge of phone dial codes: Understanding how to enter and dial special codes on your iPhone 15 is necessary.
- Active cellular service: Your iPhone 15 must be connected to your carrier’s network to send the dial codes successfully.
- Patience for propagation: Changes to voicemail delay may take a few minutes to apply after dialing the code.
How do you find your voicemail number on iPhone 15?
To change the ring duration, you first need your carrier’s voicemail number. This number is used in the dial code to set the delay. You can find it directly on your iPhone 15 by dialing a special code or checking carrier documentation.
On your iPhone 15, open the Phone app and dial *#61#, then press call. This command queries the number your calls are forwarded to when unanswered, which is your voicemail number. The screen will display a message showing the voicemail number and the current delay time in seconds.
If the code does not work or shows no number, you can also check your carrier’s website or contact customer support to get the voicemail access number. Some carriers use standard numbers like +123 or +121, but it varies by region and provider.
Knowing the voicemail number is essential because the dial code to change ring duration requires it. Without the correct voicemail number, the carrier will not update the delay setting.

**61*+1234567890**11*30#Dial this code and press call. Your carrier will update the voicemail delay setting accordingly.
