One of the main issues of Google Nexus 4 is that there is no official support of 4G LTE networks. However some of the internet sources discovered unofficial LTE support and even were able to use Google Nexus 4 at least in Canadian LTE networks Telus and Rogers. Though not officially declared  the LTE 4 support in Google Nexus 7 is indeed present in a latent state. Activation of the feature does not require any special efforts or skills.

Enthusiasts have demonstrated that despite the lack of running a signal amplifier and filter Google Nexus 4 could support 4th generation of cellular networks at least in LTE Band 4 ranges AWS 2100/1700 MHz.  Such functionality could be activated in the service menu of the device by typing the search string * # * 4636 # * # * on the virtual keyboard.

Google introduced Nexus 4 smartphone at the end of October. Google Nexus 4 is the fourth generation of smartphones sold under the brand name Nexus. Traditionally Google releases Nexus phones in collaboration with one of the largest manufacturers of smartphones. In the past, it was HTC and Samsung. 4th generation of  Nexus smartphone was developed with LG.
