Guangdong Unicom lovers short message card

It is free to set a private number and then send messages to it (the other party should also set you as private).

A month in 6 yuan (a caller ID is not 6 yuan but 3 yuan for a month. Remember to cancel)

I feel very good after using it for half a year, but the signal is a little poor. But this is also an old problem of connectivity.

The most economical use (just sending messages) is no problem if you spend 60 yuan for 9~ 10 months.

I bought the card in Changping, Beijing 100. Two cards, one for 60 yuan.
