Why Am I Still Getting Spam Calls After Blocking?

 Even after blocking numbers, spam calls can still sneak through. Here’s why this happens and what you can do about it.

---

1. Spammers Constantly Change Numbers

Scammers use random or “spoofed” numbers that change frequently, so blocking one doesn’t stop the next.

---

2. Your Number Is on Call Lists

If your number was shared or leaked online, it may appear in multiple databases used by telemarketers or spam bots.

---

3. Blocking Works per Device

Blocking on your iPhone doesn’t always sync across carriers or third-party apps — spammers may still reach you through alternate routes.

---

4. Carriers Filter but Don’t Block Everything

Even strong filters like Verizon Call Filter, AT&T Call Protect, or T-Mobile Scam Shield can miss some new spam numbers.

How to Reduce Spam Further

• Enable Silence Unknown Callers in Settings → Phone

• Use apps like Truecaller, Hiya, or RoboKiller

• Report spam to FTC (donotcall.gov) or FCC (fcc.gov/robocalls)
