GPRS Modem (help needed with AT+CPIN etc.)

[RolandD]

I recently set up a GPRS modem connecting to the internet through the standard Windows XP dail-up connection. The connection woks fine but I need to enter the pin manually AT+CPIN = "xxxx"(through hyperterminal) to enable the SIM before I can use the connection.

1) My question is if it is possible to add the AT+CPIN command to the Modem init string which already contains the AT+CGDCONT... command so that I do not have to enter it manually ? How to separate AT commands ? (I tried disabling the PIN but that does not seem to work)

2) I'm using a prepaid SIM and was pondering how on earth am I going to load a recharge voucher ? Can this be done via terminal ?

3) Also is there a way to check the usage/balance on the SIM ?

Any advice would be appreciated.

maybe a suggestion is to take the pin code request off...???

1) folow rehd's advice. place the SIM in a cellphone and disable the PIN request.

2) You can use a cellphone to process the voucher or use an online facility similar to what ABSA internet banking offers with online recharge.

3) Register at vodacom4me and you have instant access to your prepaid balance.

Hope this helps!

Tried to disable it using AT commands (which didn't work), never occured to me I can do it from a phone.

you can disable it using a AT command:
AT+CLCK="SC",0,"current pin"

To seperate commands in the modem init command box, use <CR>
AT+CPIN="current pin"<CR>AT+CGDCONT=whateva
