In practice, the average solo tradesperson gets 11–14 unsolicited calls per week. That's not a minor annoyance. At 2 minutes per interruption — answering, realizing it's garbage, hanging up — you're losing 25+ minutes every week to robocallers and lead-gen scammers. Over a year, that's 22 hours. More than half a work week, handed to spam.
The fix isn't an app. It isn't a $40/month call-screening service. It's three settings already sitting in your phone right now.
Setting 1: Silence Unknown Callers (Built Into iOS and Android)
On iPhone: Settings → Phone → Silence Unknown Callers. Toggle it on.
On Android (Pixel or Samsung): Phone app → Settings → Caller ID & Spam → Filter spam calls.
What this does is route any number not in your contacts, recent calls, or Siri suggestions straight to voicemail — silently. Your phone doesn't ring. You're not interrupted mid-job. Legitimate callers leave a message. Spam callers don't.
The objection you're thinking of is real: "But new customers are unknown numbers." Correct. That's the one trade-off. This setting works best if you're also running a call-screening layer that picks up those unknown calls on your behalf before they ever hit voicemail. But even without that, a caller who genuinely wants to hire you will leave a message. A robocaller won't.
Setting 2: Register on the Do Not Call Registry (Takes 90 Seconds)
Go to donotcall.gov and register your business phone number. It doesn't eliminate all spam — illegal robocallers ignore it — but it cuts down legitimate telemarketing cold calls, which make up a meaningful chunk of the noise. In practice, most tradespeople who do this see a noticeable drop in sales calls from software companies, insurance brokers, and "marketing agencies" within 31 days.
It's free. It takes 90 seconds. There is no reason you haven't done this already.
Setting 3: Enable Your Carrier's Free Spam Filter
Every major carrier in the US has a free spam-filtering tier that most customers have never turned on.
- AT&T — ActiveArmor Basic (free). Enabled through the ActiveArmor app or your account settings. Automatically labels and can block suspected spam.
- Verizon — Call Filter (free tier). Download the Call Filter app, activate in settings. Labels spam calls before you answer.
- T-Mobile — Scam Shield (free). Go to account.t-mobile.com or the T-Mobile app. Enables scam-likely labels and optional blocking.
- Other carriers — Check your account portal under "call features" or "security." Most MVNOs riding the big three networks have access to similar tools.
These filters run at the network level, before the call even reaches your phone. Stacked on top of your phone's built-in silence setting, you've now got two layers running simultaneously with zero ongoing cost.
Why Most Tradespeople Skip This
Because it takes 8 minutes across three different menus and nobody ever told them it was worth doing.
You're already paying for these features. Your carrier built them because the FCC pressured them to. They're not advertised because carriers would rather sell you an upgraded plan.
The real number is this: combining all three settings typically eliminates 55–65% of inbound spam volume, based on what users across the major carriers report after activation. That's not a study — that's the consistent pattern from people who've actually done it.
The remaining 35–45% is where a service like VettedCalls picks up the slack, screening live unknown callers so real customers get answered and everything else gets filtered before it touches your day.
But even if you stop at the three free settings, you're getting your time back without spending a dollar.
