I did not know that, an Aussie buddy of mine had a US dude bring him over an Eye Phone and it wouldn't work, US dude offered no help or refund, The Aussie guy should have shoved that eye phone up that pr!ck's rectum. With no lube!
I don't think Eye Phones even work in Thailand, they are locked to your home network and don't even operate on the same digital frequency bands that Thailand uses. Buy a Thai phone in Thailand, and you're golden.
