I used the package of 18 yuan (with 500 messages), and there seems to be 15 yuan (with 200 messages, and then 20 meters of GPRS. It seems that there is still a place to send colors. Please ask in the business hall for details).
Theoretically, you should be able to get two cards. Think about it-everyone wants to earn more, and you think he will be more willing!
That's all I know. I hope it helps you.
