I've been getting so much spam calls on my BlackBerry Key2 with Android 8.1 and don't even use it for calling over AT&T... haven't even gave out it's number yet not even online... I'm on AT&T here in the usa and want to know if I can stop all calls from coming in.... I've tried do not disturb but that also blocks notifications and their sounds from playing making me miss some important notifications... I tried to setup call forwarding but I am not able to on my Key 2... I'm also not able to change my number because AT&T charges a big fee to do so and I've already done a one time free number change... att also can not disable calling because it's a required part of my plan... I also can not individually block each number because I never get a call from the same number twice ever... last I'm not able to cancel my plan and set up a new one under a different number because I will loose my $20 autopay discount making my bill $10 more per month... any suggestions for what I can do? I'm getting at least 5 calls a day sometimes more... I'm also thinking about setting up a tablet based plan for my device but I don't think AT&T will allow me to do that legally under their TOS... I use text now for my calls and texts so I'm covered there.... suggestions?
