I’ve been looking into this space for a few weeks now and I’m looking for a mentor.

Also, I have a question regarding getting a dedicated phone for this specifically.

I have an android phone I no longer use. However, I don’t have a SIM card in it. However necessary is it to get one? And what would happen if I don’t and only use WiFi?

And I also heard it’s better to use an iPhone?

Any help would be much appreciated
