I have worked in translational research in the biomedical field (oncology) for nearly 30 yrs.  
 A very deep dive into the health effects confirmed for me not only that I don't want a cell phone but also I don't want and don't have wifi, bluetooth, or any smart gadgets.
 I'm not a fan of the loss of privacy either. Not that I or anyone I know "has anything to hide," just as a matter of principle.
 I was a late adopter, using a cell phone for fewer than 3 yrs, then happily smashed it with a sledge hammer in 2019 and never looked back! I moved and now live more than 3 miles from the nearest cell tower in a very rural location (find your distance here:

 Arthur Firstenberg's book, 
The Invisible Rainbow, does a good job of explaining the effects of electrical fields and EMFs on the human body. It's a fascinating read, though long.
 Acres review: "In 
The Invisible Rainbow, Firstenberg traces the history of electricity from the early eighteenth century to the present, making a compelling case that many environmental problems, as well as the major diseases of industrialized civilization―heart disease, diabetes, and cancer―are related to electrical pollution."
 Firstenberg has called for a movement of folks to ditch cell phones until safer technology is available. Not only for human health, but for the birds, bees, insects and planet as well.
 Here's a recent article on his Substack "PLEASE GET RID OF YOUR CELL PHONES NOW"

 Dr Devra Davis, an expert on the health effects of cell phones, has many talks on youtube. Here's a recent one from 6 mo ago

 Her TED talk is good as well, though getting older (2018), she details how the safety testing was rigged:
