Of Course! You have complete control over your inbox, and all voicemails are stored in your smrtPhone account waiting for you to review.
When a voicemail is received in the Inbox, it will show up in the list and you can listen to the recording and process it further.
All you need to do in order to customize your voicemail message and very simply add your own recording is to head over to My Account > Set Your Voicemail Greeting.
The voicemail message will be the default voicemail for anyone who calls you.
Click the Edit button and select how you’d like to set your message.
You can also adjust if you want to receive a popup notification for the received voicemail.
