I am a student in Shijiazhuang. I don't usually make a lot of phone calls, but I send a lot of text messages. I can use more than 500 a month. What card should I use? ...

There is a monthly rent in the m-zone You can pay the monthly rent by SMS, which is more economical. Mine is 200 packs from 5 yuan. 500 messages need 10 yuan. Moreover, if you join the group, you will only receive the Internet access fee for the fixed group in 2 yuan every month, and the point-to-point phone call is free. That is, users in the group talk to each other for free.
