The 2nd best option is this...just don't answer any calls unless you recognise the calling number. If it's a legit call, they can leave a voice message and you can call them back if you wish. If the bad guys know you answer all calls..well...you're finding out what happens. Using the suggestion I propose...you're spam calls with diminish...I get 1 or 2 spam calls per month now. It'll work if you adopt this concept.
Public Mobile is a tier 3 carrier, and Call control is a feature only offered with Tier 2 and Tier 1 carriers. If you need it, you will have to check out Koodo and Telus
