The roaming charge is calculated per kb or mb.
From the singtel website, the cost is $20 per MB.
$2600/20 = 130 MB.
A typical high res photo is about 3-4 MB. Therefore, 6 photos equal 24Mb.
I suppose the rest of the roaming charges are due to iphone being constantly connected to the vietnam 3G network and sending little data to and fro from vietnam to any server in the world.
Many iphone users are dumb users and they do not know how to switch off the data roaming feature in the handphone.
Iphone is a weird beast. It comes with the data plan locally and the users are pleased with the experiences. But, the users forget that their data bandwidth of the plans is only valid in Singapore.
