You'll need to use something like `pppd` to issue those commands and then setup a TCP/IP stack over the serial port. At that point your system will get an IP address and then you should be able to use the internet. — Michael Petch, Sep 26 '14 at 08:02

Do you use the command

AT+IFC=2,2

and

AT+CIPMODE=1

it works fine!

You are trying to use a dial-up connection, it means you have a stack tcp/ip side of raspberry pi! no the module!
