Voicemail full solution (Verizon)

If callers are getting a message saying that your voicemail is full but you have already deleted all of your voicemails on the iPhone and you can see in Settings that voicemails are not taking up any memory- dial *86 from your phone and then press & hold the 1 button. If you've had Verizon for a while you'll remember that this is how we checked our voicemail pre-iPhone. The thing is a pass code is required and I had not used voicemail in this way for more than 5 years. Luckily I remembered my pass code. You may have to call Verizon and reset your pass code if you don't remember it. Seems like Verizon has been storing my voicemails for the last 5+ years.
