The mobile phone can access the Internet outdoors, but there is no signal indoors, how to solve it.

If you use mobile data to access the Internet and lose your connection for no reason, it is recommended to:

2.Check if you have set up a mobile data restriction feature. Method: Settings - Traffic Monitoring - Set Data Usage Limit - Limit Data Use - Disable (Different models of mobile phones may operate slightly differently).

3.Try a different location or a different time slot.

4.Try to change another SIM card.

5.If the mobile data connection is still disconnected for no reason, it is recommended to connect to the wireless network to update the system version of the mobile phone. Note: Please back up the data in your device before upgrading.

If the problem persists, please bring the purchase invoice, repair card and machine to the Samsung service center for professional after-sales engineers to help test.

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.

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.

The poor mobile phone signal is because the signal will be affected by various factors such as terrain, landform, and high-rise buildings during the propagation process, and if you are in a relatively closed place, the signal will be affected. You can restart your phone, or change the SIM card to a family friend's phone to try again, and see if the signal of other connected users around you is working. If your signal problem cannot be solved, please contact the local customer service for consultation.

Based on the information you provide, the common causes and solutions for your phone not receiving calls** are as follows:

Check whether the mobile phone is in arrears and shut down, and it is recommended to pay and recharge;

Check whether the phone is set to call forwarding, turn on airplane mode, call restrictions, etc., and it is recommended to cancel and try again;

Check whether the function or signal of the mobile phone is normal, it is recommended to change the mobile phone or location and try again;

If you cannot use it when roaming to other places, it is recommended to check whether the local network signal is normal and whether the number has been activated for roaming permissions.

Try restarting or changing your phone to see if you can make calls**;

Bring your SIM card to your local office for testing or replacement.

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.
