I just bought a Koodo sim card and monthly plan ($30/mo., no data) to use with an old, unlocked Blackberry Bold. The problem is: when I try to make a call, I get a message that says I'm roaming and won't allow me to make the call. I also can't send or receive texts. When plugged into another phone, the sim card shows the messages I received, so it seems the problem is getting the sim to work in this phone. How do I get the sim card/phone combination to recognize the Koodo network?
