DTEK50 not getting emails on phone signal

Hello,

My Blackberry Curve 8520 picks up emails on my mobile phone network (EE) without the need to connect to wifi or mobile data.

My new DTEK50 does not seem to pick up emails on my mobile phone network (BT). What am I doing wrong, please?

Thanks,

Maggie
