invalid mmi code and or ussd code issue when run from stock dialer.

I have a samsung gs4 and i cant call my voicemaill *86 It tells me invalid mmi code Other timez i get the operator telling me the number i called us invalid. I also have a few apps that can start from the dialer that no longer start because of the aboce errors. I am rooted and running stock verizon firmware. My network operator is Telcel in Mexico.
I have to say it is not Telcel's fault since I can't use my dialer to run gallery vault either. The pin for that app starts with a ##1234 i.e. ## (then 4 digit pin )
