Should the NowTV Mobile Pass not work with the NowTV App (not internet browser) on your smartphone only, where you are entitled to watch only five channels with the pass which is Premier League, NFL, Arena, Racing (Horses) or News.
And a fresh download of the NowTV App from your phones Apps Store doesn't help, then you need to get in touch with NowTV live chat.
This has also happened to me. I have contacted online Help and they have adivsed that it is only certain channels that you get. However when I bought it it advised Sky Sports Crivket, F1 etc. This is a shocling service. Also now it wont work on the smartphone. Whats the point of having it???

With a Sky Sports Mobile Month Pass you just get access to 5 channels: Sky Sports Premier League, Sky Sports NFL, Sky Sports Arena, Sky Sports Racing and Sky Sports News.
The Sky Sports Day and Month Passes give you access to all 11 Sky Sports channels for the period covered by your Pass:
