HiI 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
> I want to get or view the SIM card number from the dongle
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.
> i went trough so many links but nothing worked
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"
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
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.
- Compiler warnings are like "Bridge Out Ahead" warnings. DON'T just ignore them.
- A compiler error is something SO stupid that the compiler genuinely can't carry on with its job. A compiler warning is the compiler saying "Well, that's bloody stupid but if you WANT to ignore me..." and carrying on.
- The best debugging tool in the world is a bunch of printf()'s for everything important around the bits you think might be wrong.
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.
What can this strange device be?
When I touch it, it gives forth a sound
It's got wires that vibrate and give music
What can this thing be that I found?
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.Originally Posted by Elkvis
Although I don't "just give" answers here, I at least try not to obfuscate the problem even if the user isn't helping themselves.
