Koodo customers can register their mother's phone number and have free calling to their Mom. Moms would like this a lot - their kids can phone them NO MATTER WHAT. Everybody would call their Mom if they could. Some can't - like me (she's no longer with us) - and they wish they could. They would tell everyone else who can, that they should. Right now. This can be promoted in sentimental ways, or even funny ways (like an annoying, nasal Mom "why don't you ever phone me???"""). Koodo would get points for free Mom-calling. From everyone.
