The LG Urbane LTE WebOS powered was presented at the MWC 2015 and is not around yet in the west at all , but still in Korea. However this version is now available on amazon but is not selling at a reasonable price.
Now LG is coming with two new WebOS powered thanks to the presence of a headphone jack and CDMA connectivity . The LG`s Urbane LTE smartwatch is the only smartwatch with cellular connectivity and it is the WebOS version.
The two models are: the LG-VC110 and the LG-VC200. (this last is coming to Verizon, see picture above). The VC-110 measures 56mm x 41.5mm, with a 45mm screen. On the other hand, the VC-200 has the same overall size of 56mm x 41.5mm, but its screen is listed at only 33mm. Both with mini USB port in the back, Bluetooth 4.0 LE ,WiFi,
These two models passed through the FCC.
There are currently no Android Wear smartwatches with cellular connectivity, and there has been no indication that Google would support it.
