How to find my Airtel SIM PUK (Personal Unblocking Key) code?

   • Provide your SIM card details, and they will assist you in retrieving your PUK code.

Method 3: MyAirtel App

1. Download and Open the MyAirtel App:
   • If you haven’t installed it yet, download the app from the Google Play Store or Apple App Store.
2. Log In:
   • Log in with your Airtel mobile number.
3. Go to the Help or SIM Info Section:
   • Navigate to the Help or Support section within the app, where you may find your PUK code under SIM details or support options.

Method 4: Airtel Website

What is default Airtel Sim PIN?

The default Airtel SIM PIN is typically set to either 1234 or 0000.

If you haven’t changed the PIN before, these are the most common defaults. However, if you’ve entered the wrong PIN multiple times, the SIM may become locked, and you’ll need the PUK (Personal Unblocking Key) code to unlock it. You can get the PUK code from Airtel customer service or the MyAirtel app.

How to enable Internation Roaming

To enable international roaming on your Airtel number without purchasing any pack, you can activate only the roaming service and pay as per standard rates. The process differs slightly for postpaid and prepaid users:

For Airtel Postpaid:

• You can enable international roaming (IR) service without buying any pack. Once enabled, you will be charged at standard international roaming rates for calls, SMS, and data.
• To activate IR service:
  • Use the Airtel Thanks app: Go to the app and toggle on international roaming service.
  • Call Airtel customer care: Dial 121 from India or +91-99100-99100 (toll-free) from abroad.
• Note: Once IR service is enabled, it remains active until you explicitly disable it through the app or by calling customer care.
• Caution: If you use services abroad without a pack, you may incur high charges. If your usage exceeds a certain threshold, Airtel may automatically activate a “Roam Without Fear” one-day pack to protect you from excessive charges, and you will be billed for that day’s pack.

For Airtel Prepaid:

• Prepaid users generally need to buy an international roaming pack to enable the IR service. However, you can also activate IR service by paying a service activation fee of ₹98 via the Airtel Thanks app.
• To activate IR service:
  • Airtel Thanks app: Activate international roaming and pay the activation fee if you do not wish to buy a pack.
  • SMS: Send “IRSTART” to 121.
  • Call: Dial 121 from India or +91-99100-99100 from abroad.
• Important: Even with IR service enabled, you must maintain sufficient main balance (talktime) to use services abroad if you do not have a pack. All usage will be charged at standard international roaming rates.

General Tips:

• Double-check your phone settings: Ensure international roaming is enabled in your device settings.
• Monitor your balance and usage: Charges without a pack can be very high, especially for data. Use the Airtel Thanks app to track your usage.
• Disabling IR: You can turn off international roaming anytime via the app or customer care to avoid unintended charges.

Summary Table

You do not need to buy any international roaming pack to enable the service; just activate IR as described above and pay as you use, but be aware of potentially high charges.
