Xiaomi Mi 5s Plus 4G network not working what s going on

If you can't use 4G, you can try to turn off the phone and restart it, if it still can't be used normally, you can check the mobile phone settings Mobile Network Mobile Data Options Voice and data to check whether the default is 3G, if so, you can re-select 4G, due to the difference in the specific path of each mobile phone type, the specific use method of your mobile phone shall prevail; Check to see if you've reached the rate limit or data cap. If you still can't use 4G, it cannot be ruled out that the conditions for use are not met. At present, the following conditions need to be met to use the China Unicom 4G network:

Condition 1] The mobile terminal supports the 4G network of China Unicom.

Condition 2] The current location has China Unicom 4G network coverage.

Condition 3] Use Unicom SIM card.

Condition 4] The number has opened the 4G Internet function (you can send SMS "KT4G" to 10010 to apply for activation, and the activation will take effect immediately).

If you still can't use it after meeting the above conditions, you can contact the local customer service to inquire whether the base station at your location is faulty and follow the guidelines.

It is related to the network standard that it supports.

After the phone turns off the 4G switch, the phone will automatically downgrade to the 3G network.

If the 3G network signal is poor, it will automatically drop to the 2G network.

However, the premise is that the phone supports 3G network, if it does not support 3G network, it will automatically drop to 2G network.

There are two reasons for this:

The first is that the machine is not enabled with 4G network.

The second is that the system has not been upgraded to the corresponding version.

How to turn on the 4G network on the iPhone:

1. After entering the settings, find the "General" setting, and then select "About This Mac".

2. Find "Operator" and click Update.

3. After the update is completed, you can see that there is an additional "Enable 4G" network setting option when you go to the cellular network settings in the settings.

In summary, the 4G network has been turned on.

If your card is fine, you can upgrade the phone system, and it will be fine after the upgrade, and I have also experienced this situation.

1. Apple 5S uses 4G network, first of all, it is to determine whether the mobile phone has a 4G network turn on button, and then whether the SIM card is open to 4G function, only if both conditions are met can you use the 4G network to access the Internet.

2. Click Settings - Cellular Data, check whether there is a button switch for 4G network settings, no means that the 4G network is not supported, and some mobile phones do not have a 4G network switch setting button in the process of manual upgrade, so you can't use the 4G network.

3. Whether the SIM card of the mobile phone card is turned on the 4G network; To open the 4G network, the mobile phone card needs to go to the business hall to replace the 4G card before you can use the 4G network, and the commonly used cards do not support the 4G network.

At present, only the Hong Kong version of 5S can be unlocked through AB card, and the network of mobile 4G and TDD-LTE can be used.

My own is also the Hong Kong version.,I also changed to a 4G small card.,It's also only on 2G.。 Wait until iOS updates the system, updates the list of operators, and removes the 4G shield in Chinese mainland. I don't know if you understand, in a word, wait for ios update!

Finally, I sincerely wish all the children who ask questions and do not choose satisfactory answers to buy instant noodles for the rest of their lives, without seasoning packets.

Only the Bank of China, Hong Kong Bank, Macau version, Taiwan, and Singapore can use the domestic mobile 4G

Because your phone is not a 4G version! Mine can't go up either.

Are you talking about the 4G network, which is to upgrade the mobile phone card.

The first is to turn off the wifi settings in the mobile phone completely, and then click on the wifi access point to use the wifi access point used before, which is the location of the blue arrow. Click Ignore this network, then go back to the home screen, start your phone, when your phone is turned on again, go to the wifi settings again to open to find a new wifi access point, and re-set the connection network. Then there is no router here, just simply connect the wifi of the mobile phone to it.

Re-enter the password and you're done.

iPhone5s can't connect to 4G general reasons and how to deal with it:

1. The mobile phone does not support specific 4G networks, but only supports 2G or 3G in China Unicom, China Mobile, and China Telecom.

2. If the mobile phone supports 4G network, confirm whether the 4G switch of the mobile phone is turned on.

3. There is no 4G network coverage in the area, and the mobile phone will choose the 3G network instead.

4. Go to China Mobile or China Unicom to buy a new 4G USIM card, activate the 4G function, and upgrade to 4G discount**.

5S does not currently support 4G networks.
