How to block Unknown Name

[Abejar]

Hi Everyone...!

Dis days i am getting a lot of unwanted calls on me & they are from unknown numbers. I am tired of picking up that calls. I want to block that calls on it. I tried routing it with voicemail, busy message, forward but it still comes. Please Help....!

Do one thing note the numbers you want to block & then call to the service provider & then ask them to block that number for your number. It will be done only by the service provider.

Here is the tool iMobileTool Incoming Calls Blocker 1.51 for the same you require for your blocking the unknown numbers. But not sure weather it works for all??

But hope it helps you...!
