A flip phone doesn't really stop surveillance. They still track where you are, who you call. Sure, maybe no app data, but since you don't use Facebook and such that data wouldn't be there anyway.

Just turn the phone off hasn't been enough for 10+ years.

Some paranoid peoples claim there are batteries inside SOICs that still can provide data.
