(PTA policies and telecom procedures can change. Always confirm through official PTA or your network’s helpline before taking action.)

If your SIM suddenly stops working — no calls, no SMS, no internet — it may be blocked by PTA (Pakistan Telecommunication Authority). This usually happens due to verification issues, illegal SIM ownership, or security policies.

This guide explains why SIMs get blocked, how to unblock them step by step, province-wise realities, and real problems Pakistani users face — with practical solutions.

✅ 1️⃣ What Does “SIM Blocked by PTA” Mean?

When PTA blocks a SIM:

  • You cannot make calls

  • You cannot send SMS

  • Mobile internet stops working

  • You may see “No Service” or “SIM Blocked”

📌 Simple Urdu Explanation:
PTA SIM block karti hai jab SIM verification, ownership ya security rules follow na hoon.

👥 2️⃣ Who Gets Their SIM Blocked?

✔ People using unverified SIMs
✔ SIM not registered on your CNIC
✔ Too many SIMs on one CNIC
✔ Expired CNIC holders
✔ Biometric verification failure

⚠️ 3️⃣ Main Reasons PTA Blocks SIMs

🔴 1. SIM Not Verified (Biometric Required)

If SIM is not verified through biometric system, PTA may block it.

If your CNIC expires, telecom services may be restricted.

Spam calls, fraud, or illegal usage can trigger blocking.

🔴 5. SIM Registered to Another Person

Using someone else’s SIM without ownership transfer.
