Not very good;

If it is ADSL directly hosted by Tietong, it is recommended not to use it. Because it is Tietong's broadband, the speed is relatively slow.

If it is a mobile home broadband sponsored by China Mobile and represented by China Railcom, then you can consider that it is a broadband system built by China Mobile based on the EPON transmission platform.

Judging from the current effects, it can be divided into several aspects. (1) Hotspot download link: The speed is very fast, basically easily exceeding the speed of telecommunications. But the premise is that this download link has many download shares, that is, seeds. Because, as long as there are seeds moving, especially in the same region, the download speed will be very fast. If not, and just rely on the interface between mobile and telecommunications, the download speed is generally not ideal. (2) Commonly used download links: It depends on whether the download access source has a moving server. If so, the speed will be very fast. If not, the speed is quite slow. (3) Cold spot download links: The speed is similar to that of China Telecom, because both China Telecom and China Mobile are very slow. (4) Non-voice and video chat: It is as fast as telecommunications, because the bandwidth requirements of these services are very low, so it does not matter. (5) Voice and video chat: If the other party is also moving, the speed will be very fast. If the other party is not on the same operator as you, the speed will be slower. (6) Cards, board games, and battles: The speed will not be affected at ordinary times. It is best not to play between 6 pm and 10 pm because it will cause lag and disconnection. If the game has mobile servers, consider using them during this time. (7) Large-scale online games: If the game has a mobile server, there is no difference in speed and telecommunications on the mobile server. If you insist on logging into the telecom server on the mobile network, you must do so between 1 a.m. and 10 a.m. during the day. (8) Online stock and futures trading: better than telecommunications. Because, first of all, the bandwidth occupied by these software is not high; secondly, if a business interruption occurs, China Mobile's fault response enthusiasm is faster than that of Telecom.
