A report that surfaced Monday shed some doubt on that declaration, though a subsequent check appears to back the initial no Wi-Fi thinking.
Claims that the Nexus 4 would indeed support Wi-Fi looked to come straight from T-Mobile's support website, where Android news source TalkAndroid seemed to have spotted some crucial details.
According to TalkAndroid, T-Mobile's site revealed that the Nexus 4 would support Wi-Fi calling as long as customers were willing to acquire a special GBA SIM card and "register a 9-1-1 address."
The only problem with this claim is that the T-Mobile support site doesn't actually carry that information. Not anymore, at least.
Did T-Mobile mess up?
A quick search on the T-Mobile support page reveals that Wi-Fi calling is actually not supported on the Nexus 4.
The page reads simply, "We're sorry, but this feature is not available on this device," under the heading "Wi-Fi Calling - Not supported."
But a glance at the page's byline reveals that it was modified on Nov. 12 at 10:33 a.m.
TechRadar reached out to T-Mobile for comment, and a spokesperson for the carrier confirmed that though TalkAndroid has yet to update its article, the support page in question was indeed altered to reflect the more accurate information - that the Nexus 4 will not support Wi-Fi calling on T-Mobile.
The Google Nexus 4 will be made by LG for Google, but Wi-Fi calling apps are normally specific to each carrier.
However, at this time it seems clear that the Nexus 4 will not support the feature on T-Mobile.
T-Mobile first brought Wi-Fi calls to Android devices in October 2010, though the function was already available on BlackBerry and Nokia devices.
