GalaxyS5-Thumb

Sprint rolled out support for Wi-Fi calls to a couple of handsets this February, but all other devices that don't already have the feature require a dedicated software update. Fortunately for Galaxy S5 owners, the carrier has announced plans to bring support over to this flagship device. The S5 will be able to make calls and send text messages over registered Wi-Fi networks following an over-the-air update (version G900PVPU1ANE5) that's scheduled to start rolling out today.

Update: Apparently the update should also bump HTC One Max owners up to Sense 6. This may turn out to be quite the OTA.

Wi-Fi calling is great for people who still have plans that don't supply an unlimited number of minutes or during those times when cell reception in a particular location is less than stellar, as it lets customers place phone or send text messages over a Wi-Fi connection instead.

GalaxyNote3-Thumb

Sprint started rolling out Wi-Fi calling earlier this year, but so far the carrier has only introduced the feature to a couple of eclectic devices. Now another device is making the list. Starting today, Sprint Galaxy Note 3 owners should receive an update enabling the feature. According to the change log, it doesn't look like this OTA will bring about anything else. The version number is N900PVPUCNC5.

Once the update lands, users will be able to make voice calls and send SMS messages over Wi-Fi without using up their plan (for those who don't have unlimited minutes/text).

If you're someone who reads this blog but is still waiting for the cost of smartphone ownership to drop enough for you to get one (I used to be one of you, so I know you're out there), then newcomer Scratch Wireless might have something to say that will pique your interest. This company pitches itself as the world's first truly free mobile service, and it does this by relying first and foremost on Wi-Fi access for voice and data.

Earlier today, rumors broke out across the net that, according to T-Mobile's support docs, the carrier's branded Nexus 4 will support Wi-Fi calling. Previous statements indicated that the N4 would not have this feature, so we reached out to T-Mobile for official word. Unfortunately, this was an error in the support documents and the phone will not support Wi-Fi calling after all. Here's the official word, directly from T-Mo:

You are correct, just a simple mistake in the online document.
