Hello there. I just both an unlocked Blackberry 8700g that was form T-Mobile. At the moment i want to use it with another sim card from a portuguese operator. He is giving me the message, " Data connection refused". I cannot also send text messages (sms). How do i make it work withou subscribing a data plan? Thanks, Marco
DATA CONNECTION REFUSED means no data is getting to the device
This issue may be caused by one of the following:

Sim card not valid
not sure if u found an answer but here is mine....Data connection refused has to do with the wireless connection. I had the same issue and I just turned off the wireless connection and is able to make and receive calls now.....if it asks u to turn radio on when ur trying to make a call just click yes

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...
