No text messages, no phone calls. What do you mean?

The reason why you can't send and receive short messages is that the base station in the same place has been broken for a long time, or the signal is unstable due to the channel interference of adjacent cells or the switching area of the base station. Generally speaking, it is most likely that there is a problem with the base station in that place, that is, there is a problem with the so-called BTS main equipment, which has caused the delay. What's more serious is that you can't receive text messages. Because the equipment is broken, he can't receive the air signal, so he can't send it to your mobile phone. It is recommended to call the mobile complaint phone and let them handle it. I have also encountered problems with the landlord. If the same problem occurs in more than three days, directly complain to customer service 10086, tell him your location and let the relevant personnel handle it.
