Hi :) I want to get or view the SIM card number from the dongle (the dongle will b already connected to the computer where the SIM card will be inserted into it) but the coding should be done by C programming / Language. Please its urgent i went trough so many links but nothing worked your help matters thanks in advance guys :)

Links please to relevant documentation for your specific bit of hardware.
While you're at it, also mention which OS / Compiler you're using. Though beware, if you mention TurboC is your compiler, prepare yourself for much laughter from the gallery.

So post some examples, and your comments on why they're deficient.
There's no point us finding the same information, post links, only for you to bounce back with "read it already, it's useless"
I'm Using Dev C++ but this is the first time i'm trying to interact with hardware though i said that i tried several times what i really did was copy and paste it in the page. So brother please be kind enough to at least just paste a code to just simply access the sim card number plz thanks :)
Nobody will "just paste code" to solve your problem. That's not what happens here.
I suggest you look into the Hayes AT Command Set, specifically the 3G/GSM extensions that are common. That's how I do it for a Hauwei E110 dongle. But if you get that far, I'll be impressed - most people who just want a code dump and are too lazy to even do a quick Google don't get that far.
most SIM cards work like a smart card (credit-card-sized card with a chip with 6 electrical contacts). since you're using windows, you should look into winscard.dll and its functions.
I don't think that's helpful at all, in this case. The interface electronics are far too complex for such a simple task, especially when the OP says he has a dongle. Let the dongle do the work - it almost certainly acts as an old fashioned, serial-controlled, AT-command-set-based, modem (even if it's a 3G/4G dongle). Then it's just a question of opening the serial port, sending the right AT command, and receiving the reply, rather than trying to read a differently-voltage, very sensitive, "tamper proof" SIM card directly.Quote:
