Do the contacts on a SIM card and card holder always match?
The pad location on the SIM card are fixed by ISO, and so their meaning. However how the signals are brought out on the holder is manufacturer dependant and you can't rely on all the holders being compatible. It's possible that there is some popular layout made by many manufacturers but it's not ensured.
If you are worried about errors in the datasheet, ask the manufacturer. It happens sometimes. Most probably they won't fix the datasheet for a few years but at least you'll have the right pinout.
