Xiaomi cellular network problems. Internet does not work on Xiaomi. Xiaomi mi6 turned off and won't turn on

Lack of 4G internet and problems with the SIM slot are serious problems that Mi A1 users can face, as they are difficult to identify without developer tools.

The bug found by Mi A1 users is connected with 4G connection in SIM 1 slot. An active Internet session is constantly interrupted for 3-4 seconds or 4G does not work completely.

This problem may not be relevant for all SIM cards of operators. mobile communications in Russia.

Why 4G does not work on Xiaomi Mi A1

To determine the problem on your smartphone, you need to pay attention to the USSD messages that will appear after the interruption of the data transfer and inform about the end of the session. This bug is noticeable only on 4G, since on 3G - the network works well and the Internet connection is stable.

According to the specification, the smartphone supports the 40th band (Band 40). But in practice, it simply loses the connection on the 40 band with a frequency of 2300 MHz in the TDD-LTE data mode. Using these 4G settings, the Internet on Mi A1 seems to twitch, constantly disconnecting and losing connection.

Due to this problem with the support of frequency bands, many users who bought Mi A1 with global firmware, began to complain to social networks and on the forum that 4G Internet does not work in the SIM 1 slot or the slot stops seeing the SIM card, and the phone offers "Initiate network search".

If the use of your smartphone is limited to only 3G, then this error will not create discomfort for you when working. For Xiaomi users who are accustomed to wireless high-speed data transmission, we would advise to wait for the new Mi A1 updates. Latest firmware most likely will fix bugs with 4G, SIM cards and the correct support for frequency bands.

It so happens that the mobile Internet does not work on Xiaomi, although all the settings are entered correctly, as indicated in. Sometimes this problem affects the entire access to the worldwide network, and sometimes only the 4g connection refuses to work. In this article, we will analyze the most popular solutions.

If the Internet does not work

Make sure all parameters are entered correctly. Ask the operator to send you the settings via SMS.

If the mobile Internet does not work well on Xiaomi, check if the firewall is blocking applications from accessing the Internet. To do this, open the "Security" application (green icon) - Traffic - Application Control, there look at the "restrictions" column, perhaps there is no access for programs to wi-fi and 3g / 4g networks.

Make sure that you have enough funds on your balance and that the traffic package has not yet been fully spent.

Reboot your smartphone. In any non-standard situation, reboot your device, usually most glitches are fixed in this trivial way.

Make sure you have a working SIM card. Insert it into another device and check the presence and operation of the connection.

If you are in Crimea, try turning on roaming on your device, it usually helps if the SIM card was purchased on the mainland.

Call the operator, possibly in this moment they have a network failure and after some time the work will be restored.

If the phone supports two SIM cards (for example, Xiaomi Redmi 3 Pro), it is worth checking that the Internet settings are assigned to the desired SIM card.

Check if the "Mobile Internet" option is enabled in the settings

If your smartphone has lost the Internet after flashing, check the availability in the section "about phone". In rare cases, it can be erased when the device is flashed, due to which the communication modules begin to work unstable.

If 4g is missing

Initially, you should contact the office of the operator company or call technical support and talk about your problem. It quite often happens that 4g is additional service, which needs to be connected separately, for example, this was observed with the Beeline operator.

Make sure you have a new sample SIM card. Most operators cannot launch support for fourth-generation networks on old SIM cards.

Go to the operator's website and check the coverage of the lte network, you may be in an area where this type of connection is not yet supported.

Be sure to check if your phone supports the required frequencies. For example, Tele2 uses the 800 MHz band (band 20), while Xiaomi Redmi Note 3 does not support this range. The same operator may use different frequencies in different areas, so always check this point with technical support.

Check the priority network type in the SIM card settings. Select "Preferred 4G". If after that the Lte network did not appear, and all the previous tips were taken into account, it is worth switching the device only to the 4th generation network. Unfortunately, this cannot be done with the standard settings. Enter the following characters in the dialer * # * # 4636 # * # *. You will open the extended settings menu, there select "LTE Only". Now the phone will only catch the 4g network. With this test, we find out if the smartphone can be forced to connect to 4g. After that, we recommend returning the previous (automatic) value.

If you didn't manage to go to the special menu, there is a second way, it is presented in this video.

If nothing helps you, but the phone should catch lte, you should try to do a factory reset or upgrade to another firmware, sometimes it helps.
