Blocking unwanted calls from people you hate or from unknown people is the feature I think we should have on our mobile phone by default. I personally tired up with lot of promotional calls from tele-callers. Though many banks & services offers you to register for “Do Not Disturb”, you still receive many calls from other tele-callers. Vodafone was the first to provide “Call blocking system” to help it’s consumers avoid such calls (but at Rs.99/month). But I have not yet heard of similar service by other providers.
Fortunately there is an application which blocks unwanted calls on any network. Epocware Handy’s Blacklist is a series 60 application that blocks unwanted calls. In first run options will be provided for blocking calls from your contact list, recent callers or unknown numbers. It also provided with an option of adding rejected calls into black list automatically. It also keeps log of all blocked numbers for 60 days.
The dis-advantage of software is, It will not notify you when a call is blocked. You have to check your log to know which numbers are blocked. The application is priced $19.95 (Rs.785), I think is the better option to go instead of paying monthly rental to service provider for same. Purchase this application here.
