So, I have been suffering from a self-inflicted visual voicemail problem. Its been going on for a month; but I only discovered it last night. I may have tried the Internet tethering work-around for the iPhone which apparently changed my voicemail network settings on the iPhone. I had to go in and manually enter the APN for the visual voicemail for it to work again. The setting is located in General >> Network >> Cellular Data Network > Voicemail >> APN and should be ” acds.voicemail” to work. DOH! But now its all working. I hate when the problem turns out to be me…
