This is a much sought feature in China and is offered by Tencent
One of the most sought after features for Chinese mobile users, call and SMS blocker has finally made its way onto Windows Phone devices.Unfortunately, Chinese users are the ones that will get this important feature on Nokia Lumia 920 and Lumia 820 devices.
According to WPCentral, Chinese customers who had purchased a Lumia 920 or Lumia 820 smartphone were pleasantly surprised to find out that both devices came with Nokia Spamfilter, which offered the following features:
- Block callers per mobile numbers;
- Block all SMS from specific sender;
- Dynamically block SMS containing specified keywords;
- Update the keyword database online for said SMS blocking;
- View all blocked calls and messages;
- Trace the geographic origin of specific phone numbers (only works for mobile numbers, precise to municipality and carrier).
Nokia Spamfilter seems to be “technically powered by Tencent Inc.” and, hopefully, will make it to Lumia 920 and 820 devices available in other regions as well.
