Spam and fraudulent phone calls are becoming a serious problem for millions of mobile users across India. From fake loan offers to fraudulent KYC update requests and banking scams, people are receiving suspicious calls almost every day. According to recent reports, India ranked fifth globally in terms of spam call volume in 2025, highlighting the growing cybersecurity challenge in the country.

If you frequently receive calls claiming to offer instant loans, credit cards, insurance policies, or urgent bank verification requests, you are far from alone. Experts warn that scam callers are now using increasingly advanced technologies and deceptive tactics to target unsuspecting users.

Fraudulent Calls Are Increasing Rapidly Across India

Across the country, users are reporting a sharp rise in calls from individuals pretending to be bank officials, government representatives, telecom executives, insurance agents, or financial service providers.

These callers often attempt to create panic or urgency by making false claims such as:

• Your bank account will be blocked
• KYC verification is pending
• Your SIM card will stop working
• You have won a reward or cashback
• A pre-approved loan is available instantly

The primary objective behind these calls is usually to obtain sensitive personal information from users, including:

• OTPs (One-Time Passwords)
• Bank account details
• Debit or credit card information
• Aadhaar numbers
• UPI credentials
• Internet banking passwords

Cybercriminals then use this information to gain unauthorized access to users’ financial accounts and steal money.

Telemarketing and Financial Scams Top the List

Most spam calls in India are linked to telemarketing and promotional sales campaigns. However, financial fraud-related calls and online scams have also witnessed a significant increase over the past few years.

Cybercriminals are increasingly targeting smartphone users by exploiting fear, confusion, and lack of awareness. Fraudsters often sound highly professional and convincing, making it difficult for many people to identify scams immediately.

Experts say scammers commonly target:

• Senior citizens
• First-time digital banking users
• Rural mobile users
• Individuals unfamiliar with cyber fraud tactics

With the rapid growth of digital payments and online banking in India, financial scam calls have become one of the biggest cyber threats facing users today.

Automated Calling Systems Are Making the Problem Worse

According to reports from Truecaller, spam-calling techniques have evolved significantly in recent years.

Earlier, scam calls were made manually by individuals. Today, fraudsters are using automated software systems capable of placing thousands of calls simultaneously within minutes.

These advanced systems continuously rotate and change phone numbers, making it difficult for users to permanently block spam callers. This is one of the reasons why people continue receiving suspicious calls even after blocking previous numbers.

Scammers are also increasingly using international virtual numbers and spoofed caller IDs to appear more trustworthy.

How Users Can Protect Themselves From Spam Calls

Cybersecurity experts recommend that users take proactive steps to reduce the risk of fraud and protect their personal information.

Here are some important safety measures users should follow:

Enable Caller ID and Spam Protection

Most smartphones now offer built-in caller identification and spam filtering features. Users should keep these settings enabled at all times.

Spam detection apps can also help identify suspicious numbers before users answer the call.

Activate DND Services

Users can activate the “Do Not Disturb” (DND) service through their telecom operator to reduce telemarketing and promotional calls.

This service blocks many unauthorized marketing calls and SMS messages.

Avoid Sharing Sensitive Information

Banks, telecom companies, and government agencies never ask for OTPs, passwords, or banking PINs over phone calls.

Users should never share:

• OTPs
• ATM PINs
• UPI PINs
• CVV numbers
• Aadhaar-linked verification codes

with unknown callers under any circumstances.

Be Careful With International Calls

Experts advise avoiding suspicious international calls or unknown numbers, especially if the caller pressures users into urgent actions.

Report Fraudulent Numbers

Users can report suspicious calls and fraud-related numbers on the government’s Telecom Regulatory Authority of India-backed Sanchar Saathi portal.

Reporting scam numbers helps authorities monitor fraudulent activities and block malicious operators more effectively.

Spam Calls Are Now a Major Cybersecurity Threat

Cybersecurity experts warn that spam and scam calls are no longer just a minor inconvenience. They have evolved into a major digital security threat affecting millions of users daily.

As technology becomes more advanced, fraudsters are also adopting smarter methods to manipulate and deceive people. Artificial intelligence, automated calling software, and fake caller ID systems are making scams harder to detect.

With mobile phones becoming central to banking, payments, and identity verification, experts believe awareness and digital caution are now more important than ever.

Users are strongly advised to stay alert, avoid sharing personal details over calls, and report suspicious activity immediately to prevent financial fraud and identity theft.
