Most of the time, your iPhone voicemail is full because the voicemails you deleted on your iPhone are still being stored somewhere else. At the end of each voicemail, press the number designated for deleting voicemails. This will erase the messages saved by your carrier and free up space in your voicemail inbox.

Creating a voicemail greeting might not be fun, but with the scripts I’ve shared, you should have an easier time. No need to practice time and time again — simply plug in your name, company title, and other details, then read it out loud to your phone’s voicemail greeting recorder. With a professional greeting, you’ll continue nurturing prospects even if you don’t pick up the phone.
When you leave a voicemail message, be sure to identify yourself right away. Give your return phone number at the beginning of your message so that other people don't have to listen to you twice. Speak slowly and clearly. It helps to pretend to be writing your number in the air, which will slow you down and help with clarity. Say when you can be reached.
