My phone blocks these numbers outright. Family knows to call me from known numbers.
The following numbers
011
021
031
012
063
079
041
020
010
08600
Private numbers are block as well.
As such my spam calls are limited to maybe twice a month. All my business contact knows to send emails or to arrange for video chats ect. Family member numbers or important numbers is saved on the phone, so automatically bypassed the digital filter. Started black listing sms numbers as well and they have been blocked with ruthless efficiency.
