I keep getting a notification of 2 voice mail messages on my s4 when my phone goes out of service. It is rather annoying. I do not have any voice mail messages on my phone. When my phone goes back into service the notification goes away. This started with my s3 and continues with my new phone. What can I do to get rid of this. I have poor reception in my house so this happens at least once a week where it will go in and out of service for 15-30 minutes repeatedly
