Phone number not being displayed on SM-G930T

    I purchased a pre-paid T-Mo SIM to use with a T-Mo S7, but the phone number isn't displayed when I goto Settings > About device > My phone number.  All it says is "Not Available."  I borrowed a different SIM from a post-paid Galaxy and the number shows up, so it doesn't appear the phone is the problem.  Do I need a new SIM?
