Perfect when you don’t have time to talk, or don’t want to. With our Group Messaging feature, you can even send one prerecorded voicemail to up to 10 contacts at once. And now, it’s hands-free: just say “Hey Siri... Call [contact name] using slydial!” When do you slydial? Think of slydial as your secret communication shortcut. Use it to: -Save time when you’re busy. -Respect someone’s time by not interrupting. -Get your point across when a text won’t cut it. -Avoid the stress of an awkward conversation. How does it work? 1. Open the slydial app. 2. Sign in or create a free account. 3. Choose a contact (or enter their number). 4. Slydial connects you directly to voicemail, simple as that.
