I do not have any call blocking or spam blocking add-on features on my cellular line that I know of, however I have gotten a dramatically reduced number of spam calls than I did a year ago. I still get the random duct cleaning calls, but not too often, however the CRA scam calls has almost completely stopped. I do not know of Bell Mobility has implemented this feature on the back end but if they did, I'm noticing it on my end working.
I also am getting a lot less spam text messages too .I used to get so many phishing attempts via text message and they have almost nearly stopped. Not sure if this is related or not but its still a nuisance so I did want to mention that.,
