The mobile phone signal in my cell is not very good, how can I let the telecom optimize

If you have an unstable or bad signal on your phone, it is recommended that you:

1.It may be that the signal coverage of your location is poor, and it is recommended that you restart your phone or try it in a different location.

3.If it doesn't work, please turn it off, take out the SIM card, and try to reinsert it.

4.Replace it with a different SIM card.

If the problem persists after the above operations, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local Samsung service center for testing by the engineer.

Samsung phones generally recommend the following steps to troubleshoot and deal with them:

1.It may be that the signal coverage of your location is not good, it is recommended to restart your phone or try it in a different location.

2.Connect your phone to a wireless network to update your device to the latest version.

3.If it doesn't work, please turn it off, take out the SIM card, and try to reinsert it.

4.Replace it with a different SIM card.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local service center for testing by the engineer.

1. There is no signal or the signal is relatively poor, mainly because the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation, such as the current location is in a relatively closed place, and the signal may be affected.

2. If the mobile phone signal of other China Unicom users is normal, the following methods can be used to troubleshoot:

Method 1] Turn on airplane mode, then turn off or restart your phone and try again.

Method 2] Test of changing the phone card to change the mobile phone card to the mobile phone of a family member or friend and try again.

Feedback, we will check and deal with it as soon as possible.

Reflect to local mobile and China Unicom operators to build base stations or indoor distribution systems in residential areas. Or move out.

It may be caused by the problem of the base station in the community, because the mobile phone network coverage needs to be achieved by building a base station, but some community properties charge additional fees, and residents do not understand communication technology, think that the base station has radiation, and refuse to build around the community, which is the reason for the poor signal of some communities or indoor floors. We recommend that you troubleshoot in the following ways:

Turn the phone back on and off and try again;

Swap the SIM card to a family member's or friend's phone and try again;

Check whether the signals of other Unicom users around you are normal.

If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local human customer service for verification and processing.

There's no way to change the network card.

Put boiling water and scald the phone signal.
