    My blackberry 8700 is also telling me that "data connection refused". I tried doing a hard reset by taking out the battery but that didn't work for me. I bought the phone off of e-bay and unlocked the phone. I am able to send text messages but i am unable to make or receive phone calls. I wouldn't think that I would need a data plan for phone calls and I would also assume that since I can send and receive text messages it isn't a problem with the network, but I could be mistaken...

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.

I need the unlock code for my blackberry 8700g imei- 357646003650271 on t-mobile so i can use any sim

Dear Katayha,

You can unlock your Blackberry 8700g now from HERE with Blackberry unlocking codes with IMEI. They are very best at what they provide to their customers. They have great customer service and provide high quality, reliable and most of all; CHEAPEST unlocking codes to their present and potential customers. I was reluctant to use their service at first, but once I did, I never went to anybody else because I found them very friendly and cost effective.

I hope they would give you the same friendly attitude and cheapest but reliable unlocking codes like they always do.

Best of luck :)

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.
