Bizarre question to be sure, I've ordered a Nexus 5 from the Google Play store that will not arrive until later this week. Unfortunately Koodo will be re-raising their prices as of Tuesday. It was suggested I purchase a Koodo SIM Card and activate it before then. However I thought having the phone's IMEI number was required to activate and select a plan. Can a SIM be activated without the phone? The other item I wanted confirmation on was whether I could change to my existing number after initially activating the SIM. So I could keep using my old phone on my existing network until the phone arrives. Is it possible to change numbers without a fee after initial activation?
