Causes and solutions of poor cell phone signal

The poor cell phone signal is not necessarily a cell phone problem. Poor cell phone signal may be caused by poor cell phone positioning signal, sim card failure, or cell phone system problems. Poor cell phone signal may also be caused by long-term power-on state. When the signal is not good, you can try to go to a high place or a place far away from the window to solve it, or use a mobile phone signal amplifier to amplify the surrounding mobile phone signals to improve the network quality.

Eliminate signal problems

If the mobile phone suddenly has no signal or poor signal, the following measures can be taken to eliminate the fault:

Aircraft mode

The local signal coverage is not very good. You can try to turn on the airplane mode of iPhone 1 1 in another place, and then turn it off, so that the phone will search for the connection signal again.

SIM card failure

There is something wrong with the SIM card, which may lead to poor cell phone signal. Trying to plug and unplug the SIM card again can solve the problem in many cases.

network settings

Problems with system network settings may also lead to poor cell phone signal. At this time, you can try to open the iPhone 1 1 mobile phone network settings and restore the mobile phone network settings, and then see if the signal returns to normal.

System problem

Errors in the iPhone system can also lead to poor cell phone signal. At this time, you may wish to update the mobile phone system or restore the factory settings of the mobile phone.
