LG G3 verizon unlock, sim sim unknown

Hi buy a G3 Verizon Lg unlocked in the US, when I get to Argentina I place a sim from here, and the phone works but says unknown sim and does not work the answering he said MMI is not valid.
From already thank you very much

See if you can find the APN settings for that network and ensure they are in your phone. If that doesn't work I would possibly try and find a different SIM as that one may be damaged.
