Type: EC150 & EC122, I have used a lot of modem by AT command to send/receive SMS. But this time, I want to try on 3G net card. After configing the Hyper-terminal, type "AT" and modem replies "OK". Good! Then no matter I try ATD10000 to make a call, or AT+CMGS=10000 or AT+CMGS="10000" to send SMS, it always fail. It said: COMMAND NOT SUPPORTED. So I just wonder any one has succeed in sending/receiving SMS by HuaWei 3G netcard? How to do it? Thanks!
