Since Petro Mobile works via the Roger nework if I were to buy the cheapest Petro Phone say the Nokia 1208 $59.00. Could I take the sim card out and put it into a Roger's or Fido phone and work via petro canada. Why: I would buy the prepaid refills at petro with petro points - good for 6 mths). Rogers has a great selection of phones compared to petro.
