We told you last month that Nexus 4 owners in Canada were able to enable LTE on their Nexus 4 using a few relatively easy steps. Now, users posting in XDA developer forums claim to have LTE service up and running on AT&T’s network in select areas. However, that doesn’t exactly mean any Nexus 4 user on AT&T can get LTE working… As explained by AndroidPolice, those utilizing LTE on AT&T are likely on band 17 operating at the 700 MHz frequency, but AT&T also has band 4 AWS spectrum only in select cities and possibly not even deployed:
in some, very select areas, AT&t utilizes band 4. Also referred to as AWS, the carrier has holdings on this spectrum in select markets including Phoenix, Raleigh, San Juan, Los Angeles, Las Vegas, Oklahoma City, Dallas, Chicago, Charlotte. Also Athens, GA and College Station, TX. That being said, the fact that AT&T owns spectrum here doesn’t mean it’s deployed.
The users on XDA forums didn’t share the exact steps they used to enable LTE, but we’ll update this post with the step-by-step instructions if they show up.
