Blocking voicemail on an iPhone prevents the phone from receiving voicemail messages. This can be useful for avoiding unwanted calls or messages, such as spam or robocalls. It can also be helpful for conserving storage space on the phone, as voicemail messages can take up a significant amount of space.
To block voicemail on an iPhone, open the Settings app and tap on “Phone.” Then, tap on “Voicemail” and toggle the “Block Voicemail” switch to the on position. You can also choose to block voicemail from specific numbers by tapping on “Blocked Contacts” and adding the numbers you want to block.
