How can China Unicom and China Mobile send short messages cheaply? Can I open a flying letter?

With the UP new army of China Unicom, this card rents 20 yuan every month, including 300 short messages and 30 minutes of local call time. If it is not enough, you can open a short message package of UP New Power, and the package fee depends on the situation in each region. After the short message package is opened, there will probably be hundreds of short messages. Whether it is the original UP new power tariff or SMS package, each price is only a few cents.

UP new forces send text messages to Unicom Mobile or PHS for free. It's more cost-effective than moving to the m-zone Send short messages to Unicom or PHS in M-Zone, each with 0. 15 yuan.
