Visual voicemail lets you see a list of your messages and choose which one to listen to or delete, without having to wade through all of them. A badge on the Voicemail icon tells you how many unheard messages you have. The first time you tap Voicemail, you’re prompted to create a voicemail password and record your voicemail greeting.
Listen to a voicemail message. Tap Voicemail, then tap a message. To listen again, select the message and tap . If visual voicemail isn’t available with your service, tap Voicemail and follow the voice prompts.
Messages are saved until you delete them or your carrier erases them.
Delete a message. Swipe or tap the message, then tap Delete.
Note: In some areas, deleted messages may be permanently erased by your carrier.
