php editor Xigua brings you the solution to the problem that Xiaomi mobile phone cannot connect to the 4G network. When we use Xiaomi mobile phones, we sometimes encounter the problem of being unable to connect to the 4G network. In this case, we need to take some measures to solve it. This article will provide you with some simple and easy methods to help you quickly solve the problem of Xiaomi mobile phone being unable to connect to the 4G network. Whether it is a network setting problem or a weak signal, we can solve it through the following methods and let your Xiaomi phone reconnect to the 4G network.
With the development of technology, mobile phone signals have also evolved from E to 2G, 3G, and 4G. Now we have entered the 5G era, and everyone can access the Internet more smoothly. But when using mobile phones, we sometimes encounter situations where the mobile phone has no 4G signal, the mobile phone receives the 4G signal slowly, and there is a 2G signal but not a 4G signal, causing the 4G function to not work properly. Is it a problem with the mobile phone that cannot receive 4G signal? What should I do if my phone has no 4g signal? Let's take Huawei Honor Play 8C as an example to explain how to deal with the problem that the mobile phone cannot receive 4g signal.
How to deal with the problem that Huawei Honor Play 8C mobile phone cannot receive 4g signal
1. The 4G network signal is weak
When the mobile phone does not have a 4G signal, first confirm whether there is a network in the place where it is located. You can also compare it with other mobile phones to see if other mobile phones also have 4G signals to rule out network problems. If there are none, it is recommended to try in a place with strong signal; if the comparison mobile phone has 4G but your own mobile phone does not, then it is a problem with the mobile phone.
2. Check the SIM card
1. First check whether the mobile phone card has outstanding balance. If the balance is insufficient, the mobile phone will have no 4G signal.
2. After eliminating the problem of mobile phone arrears, replace the SIM card to see if the 4G signal can be received normally.
If the same phone cannot receive 4G signal after replacement, rule out a problem with the SIM card itself.
If the phone can receive 4G signal after replacement, then the SIM card is broken and you can just change it.
3. Restart the phone
When the phone cannot receive the 4G signal, you can shut it down for 3 to 5 minutes, restart the phone or switch to airplane mode to see if the 4G signal can be received.
If it still doesn’t work, there may be a problem with the system version. Back up important data on the phone, double clear or restore factory settings to eliminate it.
4. SIM card holder
Check whether the working conditions of the card holder, measurement power supply, reset, and signal are normal. Especially for machines that have been dropped or flooded with water, focus on checking whether the card holder is damaged, welded, or corroded.
