Default Will the lg g2 att work in lebanon on a local carriee? need answer asap

The frequency used in lebanon is gsm 900, the lg g2 att is compatible with gsm 900. Will i be able to get 3g or whatever type of internet there? I checked on the att website for international travel and they said you can only call from there but thats on their network and not a local carrier so I am not sure. Need an answer fast please.
