Spam calls are more than just annoying; they waste your time and disrupt your daily routine. Whether it’s telemarketers pitching loans, fake schemes, or unsolicited offers, we all face these interruptions. Luckily, suppose you’re a Jio, Vi (Vodafone Idea), or Airtel user. In that case, there are ways to block these calls and protect your privacy. This guide will show you how to permanently stop spam calls on these networks using simple yet effective methods, including the Do Not Disturb (DND) service and manual call-blocking features. Let’s dive in! 💡
Why Are You Getting Spam Calls? 🤔
Spam calls are often made by telemarketers trying to sell products, services, or other unsolicited offers. These calls can come from unknown numbers or numbers that change constantly to bypass your blocked list. In India, these calls are a major issue, and telecom providers like Jio, Vi, and Airtel have rolled out solutions to help users block them. However, while you can block certain numbers manually, relying on telecom-specific services is much more effective. 📞🚫
The National Customer Preference Register (NCPR) – Your First Line of Defense 🛡️
The National Customer Preference Register (NCPR), previously known as the Do Not Call (NDNC) Registry, is a free service provided by the Telecom Regulatory Authority of India (TRAI). By registering your phone number with NCPR, you can block telemarketing calls from various commercial entities like banks, insurance agencies, shopping services, and more.
How NCPR Works:
Once you register with NCPR, you’ll stop receiving most unsolicited calls. However, some categories like emergency services and important communications may still get through. The registration process is simple and activates within 7 days.
How to Register for NCPR (NDNC) via SMS 📲
- Step 1: Send an SMS saying “START” to 1909.
- Step 2: You’ll receive a list of categories like banking, real estate, healthcare, and travel.
- Step 3: Reply with the codes of the categories you want to block. ✅
NCPR will ensure that most telemarketing calls are filtered out. However, you may still need to customize some settings for complete spam call prevention.

How to Manually Block Unwanted Calls on Android 📞
Sometimes, a spam call can come from a number that has repeatedly disturbed you. In this case, manual blocking is your best option.
Steps to Block Calls on Android:
- Open the Call History or Recent Calls on your phone.

This action will block the number from calling you again. You can do this with all numbers you consider to be spam.
Tips to Prevent Spam Calls 💡
In addition to DND services, here are some quick tips to reduce the number of spam calls you receive:
- Don’t Share Your Number Freely: Be cautious when giving your number to websites, promotions, or surveys.
- Use Call-Blocking Apps: Apps like Truecaller or Hiya can identify and block spam calls based on a database of known spam numbers.
- Enable Caller ID: With Caller ID enabled, you can see the name of incoming calls, which will help you filter out spam numbers.
- Report Spam Calls: Mark unwanted calls as spam directly on your phone to help improve call-blocking accuracy.
