How old? Does it take a SIM card? If it does, then yes you can use it but it needs to be unlocked. Then you'd have to buy and activate a Koodo SIM card for the $30 plan. I'd visit a Koodo Shop near you and they can set you up!
If you just want a basic text only plan from koodo you can go with their prepaid plan whichbisnonly $15 a month. You will still have to follow Sheila's steps for unlocking the phone, although koodo will do it for $35. And you need a SIM.
