prevent them from deactivating the location on the phone
You can probably do it using MDM. Unrelated to Traccar though.
I don't understand, what is MDM, how do I install it on the phone???
another way to prevent LOCATION from being deactivated on the cell phone
There is no other way.
I have traccar client installed on several cell phones, but it happens that some clients deactivate the location on the phone and the client app stops reporting, how can I prevent them from deactivating the location on the phone
