| | Re: Mystery - huge data usage while in Mexico
Not sure about the large amount of data, but I've had users complain about high charges for small amounts of data when in other countries (SE Asia).
The bill showed normal bits and pieces of data being charges normal amounts by other telcos as he travelled. Then one night a particular telco charged huge amounts for the same traffic.
I now advise users to either turn the phone off most of the time while travelling, or at least turn off wireless. Then they turn it on a couple of times a day to check email. The phones seem to regularly transfer small amounts of data, even when nothing seems to be happening, so I suppose it can just add up to a lot.
You just don't know what you're going to be charged, so don't give them the chance.
