I suspect that you won't be able to pair them successfully. The Alcatel appears to have a proprietary operating system and, looking at the manual, only supports the A2DP Bluetooth profile, (for connecting to a hands-free speaker or headset). The K480 requires the HID Bluetooth profile.
All modern PCs, Window and Apple, support HID, as do iOS and Android. I assume your Nexus and Huawei are using the latter?
