I don't really want to use data roaming while abroad. I have data roaming set to off. I believe that is all I need to do to avoid extra charges, and that I don't need to switch push notifications off. However, my question is whether push notifications will work whilst I'm abroad - but connected to WiFi. This would be very handy (possibly even make it worth buying a data roaming bolt on if this is in fact necessary). Does anyone know whether they will? I'm not asking if I need to turn push off to avoid roaming charges - I realise this has been asked elsewhere But I couldn't find whether push relies on data roaming.
