Spam calls trouble many people across India daily. These calls disturb work, create stress, and waste important time. Many users search How to block spam calls in India because they want simple and safe solutions.
Here, I will explain every easy method using Android phones, iPhones, and landline phones. You will also learn about TRAI DND registration online and ways to stop telemarketing calls quickly.
Why Spam Calls Happen in India

These problems make daily life difficult for many users. Blocking systems help reduce these unwanted calls effectively. India provides several strong tools for controlling spam calls.
