Couldn't agree more with what's been said. I have commented on this before and it's been mentioned numerous times
Even with no other half, it doesn't take much to work out your real identity.
Ever posted an ad on gumtree and listed your phone? Well Google has probably cached it
Own your own business? List your mobile on company accounts? You'll show up on numerous hits
Ever posted on your number knowingly or unknowingly on the web?? Yep, you get it...you're easily identifiable.
Made worse for me as I have had my moby for like 15 years and there's stupid adverts I placed on car forums 10 years ago that STILL show up when you search my mobile...so annoying
The decision really is to go Smart Puntphone or Non Smart phone for me. Each have their pros and cons.
I've gone Smartphone. A lovely HTC circa 2009. Wiped and I do not log into to the phone with any email address , spurious or otherwise. I installed WhatsApp from their website. You can download directly and boom. A cheaper way than SMS to chat with provders and sometimes they'll fire you some pictures.
