Bluetooth and SIM card problems

Mikescotland

benzol what network are you using? Is it by any chance a Russian network (MTC)?

Mikescotland The operator is A1 in Bulgaria, the display shows that it is connected to 4G but there is no internet (it cannot connect to anything)
The card is designed for a router, and when it is in it I have no problems with the internet, but when it is in the car there is no internet

benzol you may want to check this thread
https://forum.dudu-auto.com/d/2182-36e-2-rossiiskie-sim-karty-ne-rabotayut-usb-modem-cdc-mode/18
There is a patch at the end of the thread that sorted out the problem of connecting to a network and no Internet.
I understand it's in testing now so may or may not work for you.

The SIM card you are using may require manual modification of the APN. Have you modified the APN to match the one for your current SIM card?

Mikescotland I'll try a little later, I hope it works out.

Mikescotland How do I install the patch, after I put the Zip file on it nothing happens, in OTA it doesn't let me select it

benzol

Mikescotland I installed the patch from the topic, but there is no difference, even now I can't load Waze.

Mikescotland

benzol you need to unzip it and place the extracted files to root of the Usb, plug it in and wait until headunit show dialogue saying update detected.

benzol

Mikescotland I need to extract the zip to a clean USB, or create a root folder and extract the zip into it

Mikescotland

benzol to be honest, I updated a few times with usb with some other things on it and it worked.
Root means you put these extracted files directly to the usb drive, without any folder.

Mikescotland Thanks, I'll try it today.

Mikescotland I downloaded the archive, but I can't unzip it, it gives an error, and when I put it in its current state on the flash drive, nothing happens.

DUDU-Meng I haven't changed anything on the sim card.
Can you give me instructions on how to do this?

benzol
First, make sure the SIM card is detected. If the card is not inserted or inserted incorrectly, it is equivalent to having no SIM card.
Therefore, there are no modification options available.

DUDU-Meng The card is recognized, in the menu bar it shows full range and 4G connectivity

The files in the cloud storage are fine—others are downloading and using them normally. I'm not sure what's causing the issue on your end. It appears to be a problem with your PC or your operations. I'm not familiar with these technical issues, so I recommend seeking help from someone more knowledgeable about PCs.

DUDU-Meng I have tried it on 3 laptops and it cannot be unzipped on all three.
I am attaching a video about the sim card problem

The problem with the file was that I was trying to open it with 7z, after opening it with WinRar I could unzip it.
I unzipped it and installed it on the media, but there was no change, I even thought it was worse, at the moment it can't even load Waze for me

I'm not sure if your APN is set up or if the APN settings are correct. Please check them.
If everything is set up correctly but you still can't access the internet, it means there's an incompatibility with your carrier—it doesn't support your carrier yet. Please check the APN first.
