#1: Please help with T-mobile Phone working in China problem (781 reads) 作者: NC, 时间: 2004-7-23 周五, 10:38 — I brought my tri-band T-mobile phone to China, and inserted a sim card purchased locally here in Beijing. But it started to require a seurity code which I do not know what it is. If I switched the sim card back to T-mobile one, it started to work. Does anybody have idea about what is going on here?
