I have Pantech Duo C810. I have tried to connect via Bluetooth from my iMac and PC, I get that this device does not have the necessary services message when trying to connect. What is up with this pos phone? Why doesn’t it have the necessary services to connect to my computer? Why doesn’t the Pantech Duo C810 Bluetooth work for my computer? Are there any upgrades that will resolve this? I have a contract with AT&T. Please help. Thanks.
