Your voicemail is important. Keep in mind, this is essentially one of the first impressions the hiring manager will have from you. You need to make sure your voicemail is as professional as possible. Whether you are trying to be funny, trying to show off your singing abilities or shouting in the car with the windows down, chances are the hiring manager won’t be impressed. Go into a quiet room and record a simple, “Hi, you’ve reached Kim Costa. I’m sorry I missed your call, but if you please leave your name, number and a brief message I will get back to you as soon as I can. Thanks!” You really can’t go wrong with this. Trust me when I say that hiring managers probably don’t want to hear your high school’s fight song.
Increase the odds of getting a call back by mentally composing your message before each call. And remember, people hate it when callers state their name and phone number too quickly in voice mail messages – no one wants to listen to a message ten times to comprehend simple information. Begin by saying your name and company (if applicable). Then assume the person you’re calling doesn't have your number, so say your phone number twice. If your name is at all unusual, spell it the first time you say your phone number. Talk slowly like you were writing it down yourself. The second time you say your phone number, you can say it at your normal rate of speech. A gracious phone message is no longer than 30 – 45 seconds. Be pleasant, but also get right to the point. Keep your voice mail message to two points maximum. If you need to share more information, then say you will send an e-mail message with the rest of the details. Leave a specific message. There’s nothing more frustrating than a voice mail that says, “Hi, it’s me. Call when you can!” Even if you’re just calling to say “Hi”, tell them that in your message. End on a high note! You don’t necessarily need to say “Goodbye” at the end of a voice mail, because you didn’t really talk to anyone. Instead, try something like, “Look forward to talking* with you!”

The hiring manager loved your error-free application, and really liked the initiative you showed when you came in to follow up on your application. They have a really good feeling about you and are looking forward to having you come in to interview for the position. There’s even talk about hiring you on the spot! So, the manger dials your number and…ring….ring….ring…”We’re sorry, the voicemail box you are trying to reach is full. Please try again later.” The manager starts to think that you aren’t taking this very seriously and moves on to the rest of the applications, as there isn’t any time to waste with this job needing to be filled quickly.
If you are having problems accessing your visual voicemail messages or if you are not getting the notifications for your visual voicemails then the first thing that you should check is the mobile data connection. So make sure that you have your mobile data turned on and you can access the data without Wi-Fi.
