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 )

USSD command from Note Pro

I have a ATT Note Pro 12.2 and I'm using it unlocked overseas. Is there a way to send USSD commands on it? I would normally do this with an all but the apps are blocked from the play store. You can also do this with the dialer but that is blocked on the device.
