I use Unicom WCDMA network card. When I just finished using it, I got a text message every time I disconnected. It's been a while now, and there is no text message.

One situation: you run out of messages from the network card package!

Also, it depends on which bag you use.

300 yuan presented 50 text messages with a 3GB package.

600 yuan gives 100 SMS, and the package is 6GB.

1200 yuan, the package will be upgraded automatically, and no text messages will be sent.

Except for the complimentary part, all the above messages are charged at 1 and 0. 1 yuan.

Or use the service password to inquire in Unicom's online business hall!
