switching off data roaming
i'll be visiting the US from the UK soon, and have been advised to turn off my data roaming so I don't get some expensive surprise charges on my return!
if i turn off data roaming, does this mean I will not receive automatic facebook and twitter updates or emails (via their respective apps?)
so the only things I would receive are SMS and calls?
if I keep roaming turned off but connect to free wifi where possible, I will then receive email and twitter/facebook updates as usual?
