I live in Northern Ontario. I am about to purchase a ChildTrac GPS system for my autistic daughter. The GPS tracker works with any cell sim but I don't know what plan I should be looking at...I want to stay with Koodo, I've been with them for 3+ years. Would this GPS work with Koodo (manufacturer says yes, petro Canada mobility is their suggestion and provides 15$ free sim pay as you go at purchase). Suggestions?
