Recently, the signal of Xi 'an China Mobile is so bad that there is often no signal, no short message and no Internet access in the room.

Hehehe, the poor signal has nothing to do with being on the street. The quality of wireless signal is related to the coverage of the transmitting base station, the occlusion and interference of buildings. I suggest you call 10086 to complain. I will complain where the signal is not good, so as to improve the mobile signal service. Just complain a few more times ~
