The service should be working right away. Depending on which BlackBerry you bought, it may not actually work on Koodo's network. You also need to make sure its unlocked too. Is it unlocked? Which Curve is it?
Your network may be set to the wrong thing too. Under settings, mobile network, what network type is selected?
Also, just to let you know that none of the data boosters work on pre-BlackBerry 10 phones such as the curve you have.
Hey thanks for the reply.
I'm using BB 8520. It is unlocked(as told by koodo provider). And there is no 'network type' listed here. It only shows 'Mobile Network: Roger Wireless' and 'Network selection mode: Automatic"
You are right, probably I should change my phone.
