Вот что Симком пишет по поводу PPP:
AT+CGDATA="PPP", 1 The mobile supports Layer 2 Protocol (L2P) PPP only. Note: If the mobile is NOT attached by AT+CGATT=1 and the CID is NOT activated before connecting, attaching and activating is automatically done by the AT+CGDATA Command. Some providers require using an APN to establish a GPRS connection. So if user uses the Microsoft Windows Dial-Up Network and ATD*9… to connect to GPRS, user must provide the context definition as part of the modem definition (Modem properties/Connection/Advanced…/Extra settings.) As an alternative, user can define and activate the context in a terminal program (e.g. Microsoft HyperTerminal) and then use the Dial-Up Network to send only the ATD Command

Не можна втрачати надію. Не можна здаватися до останньої миті. Можливо саме вона, остання мить, принесе весну, яка стане початком нового життя.
