I was with T-Mobile until three months ago. I used their Scam Shield service - the app is still actually still on my iPhone. I received about 25 calls per day on average that slipped right through their service. Senior health coverage, car warranty, etc calls. All using spoofed caller ID. All using the same technique of call screeners in India or similar that then forward the calls to US companies buying the leads. I actually had a conversation with a U.S. based insurance agent that was buying the leads and told her of the spoofing and other shady techniques they use. Her response was, “They supply good leads so I keep buying them.” Anyway, I switched to Verizon and it is no better. I ended up setting my phone in Focus mode 24x7 and whitelisted almost my whole contact list. It was either that or change my phone number. Can’t concentrate on work when you’re being called every 20-30 minutes.
