I can't find any info on the manual on remote ID FOR my M30T.
I assume is remote ID compliant. Does remote ID needs to be turned on?
What cell ph  app can read the DJI drones remote ID?

Any drone that is still for sale today means that it has remote ID. It doesn't need to be turned on. It is actually illegal for manufacturers to have a way to disable it. For apps I've used Drone Scanner and OpenDroneID. Both of which are Android and there's probably more. I don't think they'll be one for iPhone because they don't allow API access to their phones wireless chipsets.

Hi, UAViator53. Thank you for reaching out. For the Matrice 30 Series, firmware versions v05.01.00.00 and newer are RID compliant. This is automatic and can't be disabled.
How do I know if my drone’s Remote ID functionality is working properly?
1. Remote ID status display on the DJI flight control app.
In DJI Pilot 2, if Remote ID is working properly, the RID icon in the upper left corner of the DJI Pilot 2 homepage will be displayed in black, and DJI Pilot 2 will display “Normal” on the Camera View, as shown in the Figure below:

If Remote ID is working abnormally, the RID icon in the upper left corner of the DJI Pilot 2 homepage will be displayed in red, and DJI Pilot 2 will display “Remote ID module error” on the Camera View, as shown in the Figure below:

2. Check WLAN to see if RID is broadcasting.
Alternatively, you can check local WLAN networks to see if your Remote ID serial number is being broadcasted. Use the DJI remote controller to start the drone’s motors and then check WLAN networks.
