My company just installed PeopleNet in our trucks. Our regular customers can connect and track their freight, so why should I allow brokers access my personal phone with questionable software? I dont care if they want to track me. That's not the point. I dont want spy/mal/ransomware on my phone.
MacroPoint IS on the google android store, so if the broker sends me the link to that, it's probably safe. But I have also had brokers send me links to other tracking programs that are coming from God knows where, and I refuse to install them. They can kiss my ass.
