I have a Droid Turbo 2 on Verizon running 6.0 I work in a building with thick walls - in the middle of the basement. I essentially have no signal, though texts work fine for me. Regardless, if I get a voicemail during the day (I do not use visual voicemail), my phone vibrates and lights up every time my phone re-discovers signal to tell me I have a voice mail. It is massively annoying as my phone vibrates about every 15 seconds. I'd love to turn off voicemail indications altogether, but can't figure out how. If that can't be done, how do I get it to stop reminding me I have voicemail?
