Not having Wi-Fi calling means you miss out on a feature that can save you battery life and offer you loud and clear phone conversations. But adding a feature associated with an individual carrier would seem to go against the idea behind the Nexus program anyway. We're not sure if the lack of Wi-Fi calling is actually going to stop a T-Mobile customer from picking up the device. Besides, without an LTE radio, and with support for T-Mobile's blazing fast HSPA+42 pipeline, there is another good reason for T-Mobile customers to pick up the LG Nexus 4.
The LG Nexus 4 is expected to launch November 13th in the Google Play Store priced at $299 for the 8GB version and $349 for the 16GB model. It will launch later next month at T-Mobile for $199 with a signed two-year pact.
