Hi,
i really dont know is this the right thread or not! if i am wrong, please pardon my foolishness.
i am working on SIM900b GSM module. in our country we have to check our balance using this command - *566# (grameen phone). it is possible to do for any operator through any mobile. but i cant do it with SIM900b. I tried the following command - ATD*566#
but it shows error!!!
is there are any other way? do i have to change any settings?
by the way, i can make voice call and send sms.
