bb verizon bis activation issue

[thabiso90]

hi. i bought a second hand blackberry tour verizon a month ago and registered bis from my sim provider(mtn in south africa) but havent been able to utilise the services...nothing has changed. the browser keeps telling me about that my device has no config service books, when i go to the service book menu it shows a list of the service books with a tick but except for the last 5....iv spent countless hours trying to find some sort of solution but with no luck, is this so called "verizon wireless" a deep hole or is it just a question of a few settings here and there. help

You will need the BIS service books from your provider. I'm assuming that you are operating on a GSM network.

Is the device unlocked?
