in India, where I live, SIM cards are common in cell phones. We do some
basic 'smart programing' on them. And recently they have introduced SIMs

I dont know much about them. But if you want I can find out.

That reminds me. What is SIM flex made by Schlumberger? Is it not
somewhere between a smartcard and SIM card? They are used a lot in
India.
