In the article " Web Access PC via mobile GPRS / WAP "in the creation of Connection" SAR ", instead of a telephone number of the remote access server, the string is * 99 # or * 99 *** 1 # which is filled.
What is behind this order? Simply a command "AT", like the good old days of dial-up modems (remember, the internet at 56kbps ....).
In fact your phone can be used as a GPRS modem, and like any self-respecting modem it is possible to send commands to the format "AT"!
The GPRS connection command is:
ATDT * 99 *** <CID>
Where CID is the context ID, ie the identifier of the profile data stored in your GPRS mobile. The data profiles are often called "WAP SFR, SFR MMS, WAP ORANGE", etc. ...
Example with a Sony Ericsson V600i SFR
Settings> Connections> Comm. data> Accounts Data:
WAP GPRS
MMS GPRS
WAP CSD
MMS CSD
World WAP CSD
Only the first two profiles are GPRS data, the others are in "voice circuits (Circuit Switched Data).
By selecting the profile "WAP GPRS" and Other> Account Info: this profile has an external ID, so this is a CID.
The command ATDT * 99 *** 1 # will initiate a GPRS connection using the profile settings CID = 1, ie the profile "WAP GPRS".
Where the mobile data profile has not already set, it is possible to specify these parameters in a modem initialization string.
This is the command:
AT + CGDCONT = 1, 'IP', 'NPA' where 1 is the CID, the IP protocol to use the APN and GPRS Access Point.
You can find the settings in "Settings" operators of the GPRS page .
