Can I change the amount of rings before Voicemail picks up

ONLY AT&T AND TMOBILE and other GSM carriers (mostly international) support this. This is a CARRIER NETWORK feature/limitation.
This will NOT work on Sprint or Verizon.
The number times your phone rings is NOT guaranteed by your carrier. If there are delays in reaching your device then the ring time will be reduced, usually because of poor signal.
You can use 1 of the 2 options listed below to change the amount of rings it takes for a call to go to voicemail.
