PS: To express my opinion, the attitude of mobile service is poor, the network speed is not guaranteed, and even dial-up internet access is not as good as it is. In a few days, it is said that it is an agent Unicom and a cooperation with Tietong. Do you think this service provider can guarantee it well? If you don't want to be timid, telecom operators are expensive, but at least the speed is guaranteed.
Dude, don't open those packages for so-called bargains. Looking back, there is no place to cry, really.
Thank you very much for answering your questions. I wish you a happy new year in advance ~
