I'm posting here instead of a dedicated Android forum because there will be iPhone users here who've had the same issue with Android (I hope). For my sins I'm on a business trip to West Africa at the moment and the data roaming costs are quite hideous (£8 per megabyte and the phone used six of these in no time flat, without me daring to launch the Facebook app). Here is what I want to do: - Little emailing over 3G, but only when away from the hotel WiFi - I don't mind notification (i.e. from Facebook or Tweestcaster) as long as these are kilobytes. Mail is set to sync two weeks worth of emails and download 50 kilobytes per message received on the phone. Is there any way further reduce data consumption, beyond never using things like Facebook when away from hotel WiFi? The Android phone in question is a Galaxy S3. Prior to the S3, I had a 3GS which was quite a bit more frugal with the data. Prior to the S3, I had Blackberry, which was ultra frugal with the data.
