Why does the phone have no signal at home, the phone has no signal at home, and there is a signal ou

Mobile phone no signal is mostly a problem of network coverage, first of all, you can put your mobile phone card on other mobile phones to see if it can be used, if it can be said that your mobile phone is indeed broken, if it still does not work, that is network coverage, there are many factors that affect network coverage, such as whether there is a source of interference around your home, or something that can absorb the signal, in addition to indoor items and materials, the placement of items, or sometimes the anti-theft window on the window and other metal problems, which may affect the signal, If it is confirmed that it is not the above problem, you can try it at the neighbor's house on the same floor of your house to see if it is in the same situation as in your home, if so, you can call 10086 to reflect, if not, you can consider rearranging some items in the home, and try to keep metal items away from doors and windows.

In addition, I advise you that you must pay attention when repairing your mobile phone, you have to watch them repair, otherwise they will replace the good parts in your mobile phone with refurbished, and promise that you can come to them at any time if you have a problem, and give you free repair, but the cost of accessories must be paid by yourself, so that you will lose a lot, if there is no warranty period, try to go to the regular after-sales maintenance, don't be greedy!

If you have a suite, you can easily have this problem. Because the steel structure has formed a rating, it is easy to be hungry when installing anti-theft windows.

o,Yes,Is there something wrong with your mobile phone?,I don't know if I look for someone to see it?

The phone has no signal at home, and there is a signal outside. What's going on

First, see if your current position is out of the signal blind spot, the blind spot includes outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not yet been built, as well as urban signal mobile phones are shielded and blocked signal can not be covered, such as office buildings, bar rooms, elevators, underground places, buildings and other places. Solution: Step out of a field where there may be no signal and dial ** in a wide area.

Second, if there is no problem with the location, it may be caused by interference facilities, the mobile phone receives signals through the propagation of electromagnetic waves, so the base station establishes a connection between the transmission of radio waves and the mobile phone, so as to achieve the purpose of voice call. Interference from electromagnetic waves can affect mobile phone signals, which usually occurs in the test room. Workaround:

Look for the surrounding signal jamming devices and turn them off or remove them.

You can do it from a window or balcony, because the base station is far away from yours and the signal is weak.

If there is no signal on your phone or an emergency call prompt is displayed on the screen, it is recommended:

2.If it is a dual-SIM phone, please check whether the SIM card is activated: Settings - SIM Manager - SIM1 SIM2 - Click the SIM card icon - slide to turn on (the operation mode may be slightly different for different models of mobile phones).

3.If there is still no signal, it is recommended to turn off the SIM card and remove it, wipe the SIM card chip with an eraser, and then reinstall it.

4.If it doesn't work, try to change to another location to rule out whether it is caused by poor signal coverage in your location.

5.Try to change the network mode to 3G or 2G (do not select the auto-connect mode). Note: Some machines do not support changing the network mode.

6.Try to change another SIM card.

7.Update your phone's system version: Settings - About Phone (About Device) - Manual Update Automatic Update (Software Update System Update - Update). Note: Please back up the data (contacts, messages, **, etc.) in your device before upgrading.

Summary. Hello, dear <>

The stability of the cell phone signal is affected by a variety of factors, including but not limited to the following:1Base Station Signal Strength:

If you have a weak signal from a base station near your home, it may cause your phone to not receive a signal. Outdoors, there may be better base station signal coverage due to the influence of terrain, buildings and other factors. 2.

Frequency band differences: Different carriers use different frequency bands, and if the frequency band supported by your phone does not match the base station signal band in your area, it may cause unstable signal reception, even if the signal strength is the same. 3.

Obstruction of buildings: Obstructions such as buildings may affect the transmission of mobile phone signals. Especially in places such as closed rooms or basements, building occlusion can be more significant, which may lead to missing signals or unstable reception.

4.Mobile phone hardware problems: If the mobile phone antenna is partially damaged, contaminated with dust, etc., it will also affect the reception quality of the mobile phone signal.

If you don't have a signal at home and you have a signal outside, it's most likely due to the reasons mentioned above. It is recommended that you try to place your phone near a window or use an external antenna to enhance the signal to improve the signal reception. In addition, if necessary, you can also contact the customer service of the local operator for further information and solutions.

If you don't have a signal at home, but you have a signal outside the dismantled limb, it's likely due to the reasons mentioned above. It is recommended that you try to place your phone near a window or use an external antenna to enhance the signal to improve the signal reception.

<>I've lived here for more than a year, and the signal is normal, but it's not normal these days.

It's not because of the phone.

It's not a base station, but it's probably a nearby base station for maintenance.
