I have verizon , and I'm on a plan . About 2 months ago I got mad at my ex which is also on verizon and told my mom too block his number , we are working things out now..but my mom won't unblock it , he has verizon too and I was wondering how long numbers stay blocked for ? I've heard 90 days but I'm not sure if that's true , 10 points - best answer
