If your device is locked on a particular wireless provider, installing sim-card from another wireless provider may cause this message.
If you want to use locked device with sim-card from another provider - you need to unlock your device.
Get a device unlock code to unlock your blackberry.

The problem is: I unlock 9530 before, from Verizon but it used to accept other SIM CARD.
This one, do not accept it, and when you go to:
SIM CARD: No Valid SIM Card
and when you look in it is like:
Service Provider disabled
So, if you got some idea.

I have an unlocked Blackberry 9700. When I go to the country where I work, they give me a SIM card to use while I am there.
I just got the Blackberry and I would like to know if there are any problems in removing the BELL SIM card and replacing it with the new SIM provided, and changing it again when I get back home.
