I am trying to add LTE module in vim3l board. So that I have some doubte.
When we are adding LTE module so that any changes require in the source code which i have donwload for the vim3l pie version.
Is there any document available for 4G LTE support in vim3L
How we can configure and add file like calling, chat and every think for the vim3l and how we can get service and app in the my source code which i have download with official side .( Download The Android Source Code | Khadas Documentation ).
I didn’t got any file from modem vendor and when i connected “quectel em06-e” module it’s showing no sim found on the system. Is there any functionality for calling and chat. “libquectel-ril.so” is already available and I didn’t get any file from khadas when I order this module.
I have ordered the module from khadas site only there was two option one for Asia and another for US/Europe We have bough the Asia one. We are connecting according to process and we are checking for the sim detection for cellular but it’s displaying no sim card connected. “Quectel EM06 4G LTE Module” for the asia one.
I are using Airtel and i have checked that sim is not locked,inactive and cellular service is also working fine on the mobile but when i connecting on the board it’s not working you can see on the image.
I have connected antenna. Even there is 3 port to connect antenna C,G,D port I have connected all one by one and also check SIM position but still it’s displaying No SIM card.
When we are trying to downoad img file from official side that time it’s detecting sim but network is not coming but when we are trying to flash our source code img which we are downloaded from official side that time sim not connected issue is coming.
Note:- 1. Network is not coming on the downloaded img file from khadas page.
2. No sim card connected issue is coming in the our source code which we have download from the official side and build after that flash on the board.
I am getting detection sim when I am trying to check with the firmware .img file() which is available on the official side But when i am trying to check with my code which i have downloaded from side and build that source code after flashing it’s not detecting.
When we are flashing official firmware .img file it’s showing network icon without sim but with sim it’s detecting sim and working fine.
When we are flashing our source code which we have downloaded from official link after build flashing it’s not showing network icon and also not detecting sim it’s showing only sim not connected.

Obviously there’s something wrong with your build firmware. Before making any changes, we should start from the following two aspects:
Ensure that the downloaded code is complete and correct
@goenjoy
Now sim module is working now. Thanks for your support.
I have one query. I am looking for the device which I can connect through khadas vim3l board and it’s able to create wifi. That device should connect directly through the optical fiber cable for the internet.
