A short message on my mobile phone is unclear.

If you don't use the network, you should turn off the GPRS data connection in the settings, otherwise sometimes you will run traffic if you accidentally open the browser or other applications, and some mobile phones will run some programs in the background.

1m = 1024k, 0.31MX1024x0.0/= 3.2 yuan.

Therefore, it is more cost-effective to quickly close the data connection without surfing the internet, and it is necessary to use monthly traffic.

Take it if you are satisfied. I seldom come to answer questions, but I want to ask questions and find out what I didn't ask. Ha ha.
