Is this bluetooth headset?

Connectivity AC power supply -USB power supply by PC Bluetooth device - No Connection (mini jack, USB, etc.) - USB 2.0/3.0, 3.5 mm jack Cord length - Control cable: 95 cm, HS cable: 120 cm

Can this be connected to Smartphone, desktop and laptop

It can be connected to android phones via 3.5 mm jack (single pin) and with laptop via both - usb point or the single pin. Headphones cannot connect to iPhone! This I feel is biggest drawback! After paying such money it should also be compatible with iPhones.

What is a difference between jabra evolve 40 ms and jabra evolve 40 uc?

The models that are certified for Microsoft Skype for Business (or Microsoft Lync) support Microsoft Skype for Business as a Plug and Play experience. The Plug and Play experience includes these benefits: Automatic selection as the default audio device. Features to answer and end calls, adjust volume, and mute. If multiple certified audio devices are present, certified models also offer call prioritization. Microsoft Skype for Business will correctly send the audio to the device that was used to answer an incoming call. If you use a model that is certified for Microsoft Skype for Business with a different computer telephony (softphone) client, the product should work the same as a UC model regarding audio and features (such as answer and end calls, adjust volume, mute). If you are not using Microsoft Skype for Business, use the standard UC model. Regards Jabra Connect India Pvt. Ltd.
