TiL I have a problem with mobile data. The network disappears spontaneously and starts after a while. Today I restarted the device 5-6 times, but the network does not activate. After about three hours the network activates after another restart I reset the device two months ago, but the problem remained. The OTA update came soon, but I still have the same problem. https://youtu.be/zc-Ph9av55w?si=8nzLbMWRweYlYxRA
DUDU-Meng TiL Please remove the SIM card. Place a piece of paper under the card to elevate it and apply more pressure for testing.
TiL Yesterday it refused again and hasn't worked for two days now. I followed the recommendations, but to no avail.
DUDU-Meng TiL Please try updating this firmware. If the issue persists, it is likely that the SIM card slot is faulty. https://drive.google.com/open?id=1drFMbSGlzpU5EV0BtV1W_bnnaJWFw9m4&usp=drive_fs
DUDU-Meng TiL Extract the 7Z compressed file to a USB drive. Insert the drive to automatically detect and perform the upgrade. The offline upgrade feature cannot be used.
