My MacBook had been on loan to my daughter for a month or so and my account hadn’t been logged into for as long. So when I connected via my phone’s data connection DropBox and Photo Stream/iPhoto syncing started.
I only realised that some major syncing was going on when I stopeed and thought about why the connection was a bit sluggish (given that it should be clocking 45 Mb/s).
In an hour or less of syncing I had promptly burned through more than 1.5GB of data. This pushed me into excess data usage and so far I’m facing at least $35.00 of excess usage with still more than two weeks to go before the plan clicks over. Over course I didn’t realise all of this until I got text message from Optus the next day.
So the lesson is…
So the lesson is make sure your devices are synced fully before travelling and then disable DropBox, Photo Stream sync or any other data-hungry syncing apps you may have. Also watch your general web browsing. Because the speeds are so fast it is much easier to burn data through normal web browsing. Greater speed = faster browsing = more page loads =more data used.
