I believe you can play Boost(Fast Fold) with mobile, but I'm not very familiar with their mobile platform. Currently Boost only really ever runs with any decent traffic at 10NL.
The traffic overall is pretty good and getting better. The Chico Network is ranked 14th in the world for poker traffic according to PokerScout.

Cashouts are pretty quick, easy and reliable. I would recommend using Bitcoin if possible.
