hey everyone, i bought a new 9700 unlocked bb...works amazing with the sim card of the network i bought it from, but when i put another different sim card (from another carrier) the wifi stops working and i cant connect to any wifi network...why? and how to solve this? just to mention that calling/receiving calls works just fine with any sim card/any carrier..

Who is the second carrier?

Do you have a BB data plan with the second carrier? You will need the appropriate service books from carrier 2 to use BB services.
