Over the last few years, millions of Indian smartphone users have noticed a bizarre and irritating trend: waking up to missed audio or video calls on WhatsApp from unknown international numbers, most commonly starting with country codes like +84 (Vietnam), +62 (Indonesia), +254 (Kenya), or +92 (Pakistan).
If you receive one of these calls, do not call back, and do not reply to their "Hello" message.
You are not receiving a misdialed call. You are being targeted by highly organized, automated cybercrime syndicates. Here is exactly why this is happening, what the scammers want, and why traditional messaging apps struggle to stop it.
What is the International Missed Call Scam?
This tactic is a modern adaptation of the classic "Wangiri" (Japanese for "one ring and cut") telecom scam. Scammers use automated software to dial thousands of Indian numbers simultaneously. The software is programmed to ring only once or twice before disconnecting, leaving a "Missed Call" notification on your screen.
The scammers are banking on human curiosity. When you see an exotic international missed call, you might wonder if it's a distant relative, a business opportunity, or an emergency.
If you call them back or send a text asking "Who is this?", you fall into one of three traps:
- The Number Verification Trap: By reacting, you signal to the automated software that your phone number is active and monitored by a real human. Your number is then marked as "high value" and sold to other scammers for future phishing attacks.
- The Fake Job Offer: The scammer will reply with an incredibly lucrative part-time job offer (e.g., "Earn Rs. 5,000 daily by liking YouTube videos"). This is the start of a massive task-based extortion scam.
- The Video Call Sextortion Trap: If you call back via video, the scammer (often playing an explicit pre-recorded video) will immediately screenshot your face next to the explicit content and threaten to send it to your contact list unless you pay an extortion fee.
Why +84, +62, and +92?
It is a common misconception that the scammers are physically located in Vietnam (+84) or Indonesia (+62). In reality, the scammers could be sitting anywhere in the world—even within India.
They use these specific country codes because virtual VOIP (Voice Over Internet Protocol) numbers from these regions are incredibly cheap and easy to buy in bulk online. A scammer can purchase a block of 1,000 virtual +84 numbers for pennies, without ever submitting a passport, ID card, or legitimate KYC documentation.
The Core Problem: Global Anonymity
Why is your WhatsApp flooded with these calls? Because traditional messaging apps were built on an unverified honor system.
On legacy platforms, anyone with an internet connection and a $1 virtual number can create an account and immediately start calling anyone else in the world. The platform does absolutely nothing to verify the real-world identity of the person holding the phone.
This global anonymity is a feature for users, but it is a superpower for cybercriminals. It allows them to harass millions of people with absolute impunity, knowing they can simply delete the virtual number and vanish if they are caught.
How AirlockChat Eradicates Anonymous Spam
To stop international spam rings, we have to remove the anonymity they rely on. This is exactly why AirlockChat was built.
AirlockChat is fundamentally hostile to anonymous spam networks:
- Mandatory Government ID Verification: You cannot simply buy a cheap virtual number and create an AirlockChat account. Every user must authenticate their real-world identity using a government-issued ID (like DigiLocker).
- No Anonymous Harassment: Scammers running the +84 missed call scam will never use AirlockChat because it requires them to tie their fraudulent activity to their legal, verified identity.
- Absolute Sender Certainty: When your phone rings on AirlockChat, you know with 100% cryptographic certainty that the person calling is a verified human being, and you see their legally verified name on the screen.
Key Takeaways
If you receive an unexpected missed call or message from an international number on WhatsApp:
- Do not call back.
- Do not send a message asking who they are.
- Block and report the number immediately.
If you want a communication experience free from anonymous spam, international bots, and extortion attempts, switch to an ID-verified network. AirlockChat is available for free on iOS and Android.
