Pls I will like to learn more about the sim card production Process based on my course of study, pls anyone who has an idea on which language is used to program sim card chips should help. Thanks

Oh boy!

they dont program sim card rather they program ussd

Go and read up on JavaCard technology that is the modern way to do it.

Alright, thanks, I'll do just that!

SIM cards are not programmed per se. They are created like the chip on an atm card. Their main aim is to securely identify a user while ensuring secure communication between the device utilising the chip and an expectant communication system.
The systems(atm, mobile phones) that validate these sim cards, are programmed to ensure that the sim cards are valid and registered on the system ensuring that only authorised sim cards are allowed for use.
If you specify your question I can give a more specific answer.

Actually simcards are programmed and applications are installed on sim cards. I was once contracted to do that. Just for corrections.

thanks alot, im currently thinking of a way to have a mobile phone without a sim card, but still each device will have its own id such that, if there are many of such devices, you can specify which one you want to cover and i believe that is done with sim cards on a normal phone.
i am thinking of optimizing a mobile device that can communicate within themselves without the help or our money zapping network providers in the country.

You are thinking of a two way radio

What you are asking is in the field of embedded systems programming, yes Sim cards contain chips and have programs burned into them, so google more on stuff like embedded C, Verilog, also research into PCSC SIM-Programmer (its a device)

Alright, I've been doing a lot of readings lately, thanks to you all for giving me these pointers.

Sort of. But just that I want to have many radios and I want to be able to connect a particular one at a time without other radios receiving the information the selected radio is receiving.
