[TESTING] - NAND OMGB (1.2.3)

[jotarou1]

Hopefully this is an easy one.

My carrier is Sprint. I can make/receive calls, data, text all working. But when somebody leaves me a voicemail and I try to listen to it, I get a message that says "The feature code you've entered is not valid"

My phone dials *86 to get to my voicemail.

Is there a setting I need to change?

EDIT:
When I call my cell phone from my work phone, I can check my voicemail that way pressing * then entering my passcode.
