here is the error message

回答: Nor sure.Does the phone read the China SIM?bigboy20002012-04-02 07:36:48

using 聯通card in China.

Preferred network has three options:
CDMA -- did not work, because it is gsm sim card
Gsm mode-- did not work, "there is no sim card on your device, your device will switch to CDMA mode now"
Gsm/umts mode -- did not work, same error message as above.
