Lock Down Their Phone
Settings, apps, and call blockers that turn their phone from a liability into a fortress
Open interactive version (quiz + challenge)Real-world analogy
What is it?
Phone lockdown is the process of configuring your parent's smartphone settings, installing call-blocking apps, and setting up VIP contacts so that scam calls never ring through while legitimate calls always do. It transforms the phone from a source of anxiety into a protected communication tool.
Real-world relevance
A grandmother was getting 8-10 spam calls per day and was exhausted from the stress. Her daughter spent 30 minutes enabling 'Silence Unknown Callers,' installing Truecaller, and setting up Favorites. Two weeks later, she had received maybe one spam call. For the cost of 30 minutes and one free app, her phone went from a source of constant anxiety to a tool she enjoyed using again.
Key points
- The Scale of the Assault — Americans receive 29 billion spam calls per year according to FTC data. Older adults receive significantly more scam calls than younger adults, and many stop answering their phones entirely out of fear -- isolating them from legitimate contacts.
- Silence Unknown Callers (iPhone & Android) — This single built-in feature is the most effective spam blocker. When enabled, calls from people not in your parent's contacts go straight to voicemail without ringing. Legitimate callers leave a message; scammers waste their time. Works on both iPhone and Android.
- Set Up VIP Favorites — After silencing unknown callers, set up 3-5 Favorites (children, siblings, close friends) so their calls always ring through regardless of settings. On iPhone, use the Phone app's Favorites tab. On Android, star important contacts.
- Install a Call-Blocking App — Third-party apps like Truecaller maintain databases of known scam numbers and block them automatically. The free version is effective for most users. Other options include Roboshield, Hiya, and Mr. Number.
- Enable Two-Factor Authentication — A hacked Apple ID or Google account gives scammers access to passwords, photos, and financial information. Two-factor authentication means a scammer needs both the password AND a verification code sent to the phone -- stopping account takeover cold.
- Test Everything Before You Leave — After setup, test: call from your number (should ring), have someone call from unknown number (should go to voicemail), verify your parent knows how to check voicemail. Document what you configured and leave written instructions.
- Additional Steps in the Book — The book covers additional phone hardening steps including Do Not Disturb scheduling, Find My / location sharing, Medical ID setup, and more. These take an extra 15 minutes but provide comprehensive protection.

- 1. PHONE LOCKDOWN CHECKLIST -- This is your step-by-step guide to securing their phone in about 30 minutes.
- 2. Step 1: Silence Unknown Callers -- This is the biggest win. One toggle stops most spam calls instantly by sending unknown numbers to voicemail.
- 3. Step 2: Set Up Favorites -- Critical safety net. You don't want to block your own calls! Add 3-5 VIPs whose calls always ring through.
- 4. Step 3: Install Call-Blocking App -- Truecaller adds a second layer by identifying and blocking numbers from its database of known scammers.
- 5. Step 4: Enable Two-Factor Authentication -- Protects their Apple ID or Google account from being hacked, which would expose passwords and personal data.
- 6. Step 5: Do Not Disturb for nighttime -- Scammers love calling at 2 AM when people are confused. This ensures only Favorites can ring through at night.
- 7. Step 6: Find My / Location Sharing -- Not directly scam-related, but gives you peace of mind and helps locate a lost or stolen phone.
- 8. Step 7: Medical ID -- While you're in settings, take 5 minutes to add emergency medical info. Could save their life in a real emergency.
- 9. Step 8: Test Everything -- Never leave without testing. Confirm your calls ring, unknown calls don't, and your parent knows how to check voicemail.
- 10. Step 9: Follow Up -- Check in after one week. Some legitimate callers may need to be added to contacts. Minor adjustments make the system better over time.
