I researched this online for hours and didn't find a solution that worked. I am an AT&T subscriber so I called their help line. The first level CSR wasn't able to solve the problem so she turned me over to tech support. I have to hand it to him, he spent a minimum of 2 hours trying different things and nothing worked. I suggested to him that maybe this was a Samsung problem. He was kind enough to connect me directly to Samsung. He introduced me to Dee and she told him she would take care of me so he hung up. Once he hung up, so did she and I never received a call back. So again I called AT&T and they gave me the number to Samsung. I got a different rep and he said he couldn't help me unless I could provide him with the IMEI number. He explained that all the carriers customize the phone and without this number they wouldn't be able to help. I had to hang up my cell phone to look it up and then call again. The third gentleman I got on the phone tried several different things. By now I am pretty familiar with the different settings but there was one so well hidden I didn't know it existed. He said to go to the main "Setting" (not the phone setting or message setting which are different) and click on "Application Manager". Right under "Application Manager" and above "AllShare Cast" there is a line that says " Download Running All". You have to scroll to the left to even see "All". He told me to scroll down to Voicemail. After that exercise we both learned my phone doesn't have voicemail listed even though I can pick up my voicemails. The Samsung Rep said I could take it into AT&T to see if they can fix it or send it to Samsung. If I send it to Samsung, there are several steps I need to take first and will loose my phone for approximately 2 weeks. His explanation sure discouraged me from sending it to Samsung. The moral of this long story is if this is an important feature to you like it is me, don't buy a Samsung phone. And good luck if you ever have to use their customer service. Here is their help number if anyone is interested. 1-888-987-4357
