Those steps might make you feel better but buy you very little in terms of privacy. Your telecoms provider will still know roughly where you are at all times, they have to, it's how their switches know which towers to route your traffic to and from.

Unless you tunnel all your data traffic they'll also get copies of that and may sell pseudo-anonymous website usage statistics to one of the web metrics businesses. In some countries they also intercept and modify web content that you might view.

And what can you do about the baseband radio processor and its code? Nothing. Assuming you have a tunnel in operation, the phone could still be collecting and quietly sharing metadata and you'd never know.
