Hi. Sorry can you let me know how to block the private call(with NO number appear)? I am not able to do with my BlackBerry Classic. To block the private phone is very important. Tanks
Solution : The phone number which is not even listed in phone memory will not blocked by application. If user enter any number as unknown or as private number, Those numbers can blocked. If you received a phone with masked number and users phone didn't get number from their service providers, it means their is no phone number memory in your BlackBerry device. These numbers can not blocked.
