Is it true to rent a mobile phone card in October?

/kloc-there is still a card rent in October. Take China Mobile as an example.

One is really free of monthly rent and caller ID fee. But there is a charge for answering the phone, and the cost of dialing out is relatively high. There are not many such cards now.

The other is free of monthly rent, but there is 6 yuan caller ID fee (now changed to "communication service package").
