I am from vietnam. This tissot i bought and paid online through website and visa, first time i have a little scare but when the joma ship for me, it was a great experience!
I have a apple store in the south of viet nam. I usually have iphone's imei need to unlock, such as t-mobile. And i found cellunlocker.net, it was awesome, fast and i feel this is the cheapest site that i know to now.
