I've got the old $15/month plan with 50mins and 50texts but I'm really starting to need caller id as I keep missing very important calls. I can't seem to find a caller id add-on in self serve. Anyone know how I can get it and how much it might cost me? Also, the current cheapest Koodo plan ($30) with caller id is a bit too much for me and has way more than I need so that's not really an option. Thanks a lot for the help.
