Re: Data connection refused

DATA CONNECTION REFUSED means no data is getting to the device
This issue may be caused by one of the following:
There are communication issues with the wireless network.
The BlackBerry smartphone does not have the correct service plan enabled for the account.
Cause 1
There are communication issues with the wireless network.
Perform a hard reset. For more information, see KB02141. If this does not resolve the issue, contact your service provider for more information regarding the wireless network communication.

Cause 2
The BlackBerry smartphone does not have the correct service plan enabled for the account.
Make sure that the correct service plan is enabled for the BlackBerry smartphone user's account. Please contact the service provider to enable the correct BlackBerry smartphone service plan on the account.

Dear Carol, puk code can be found at your sim card package usually written on small paper in your sim card bundling when you bought that phone at first time. However if you can't find that you can call your provider and asking them about your puk code and it's free. That code can be used to unlock blackberry 8700 password and prevent your sim card blocked but you will lose all your previous data in after your blackberry unlocked.

The unlock code is specific to each Blackberry. it starts with ## and then has a 4 to 6 digit number. If your provider is T-Mobile, then they have the unlock codes for your Blackberry.
