Yes, you can bet on Betfair from your cell phone. Betfair offers a mobile app for iOS and Android devices that allows you to access their platform and bet online from your phone. Here you can place bets, deposit and withdraw funds, watch live streams, check stats and much more. Alternatively, if you prefer not to download the app, you can log into Betfair via the mobile browser, which has exactly the same features as the mobile app.
