Alright so i'm pretty new with unlocked phones, this is gonna be my first one. First of all, is the play store's nexus 5 compatible with a koodo micro sim card? and can i just put the sim card of my phone into the nexus 5? or is there a whole other process with the works.
Yes, the Nexus 5 from the Play Store is fully compatible with Koodo.
If your current phone uses a micro-SIM, then all you need to do is transfer the SIM to the Nexus 5. Otherwise, you'll have to purchase a micro-SIM from a Koodo kiosk or a retail partner and make the switch under the Phone tab in Self Serve.
