T-Mobile servers seem to block or transform double-byte character transmissions. Either your 7290 will not receive it, or the Chinese characters will appear as blocks or question marks. I wasted literally eight hours talking to T-Mobile technical support people trying to get a straight answer. I finally gave up, and I am seriously thinking about dumping T-Mobile. Here's the idiot problem. A T-Mobile device cannot send or receive Chinese characters, yet a roaming device (e.g. from Smartone Hong Kong) can send or receive Chinese characters while roaming on the T-Mobile network. I suspect that the T-Mobile SMS servers strip a bit and convert all 8-bit transmissions into 7 bits. My BlackBerry 7290 will not even receive an SMS message if it contains Chinese characters. My friend's non-BlackBerry mobile phone receives such an SMS with all the Chinese characters converted into little blocks. Idiot T-Mobile.
