One of the things that has been rolling out across Sprint’s lineup, and has long been a part of T-Mobile’s, is the ability to do WiFi calls. This takes the load off of severely overstressed and antiquated cell towers by routing your calls through the connected WiFi hotspot.
In theory WiFi calling is an energy saver, and most WiFi calling modules I’ve seen include the ability to turn it on and off by WiFi AP (such as use the WiFi at work, don’t use the WiFi at home). But what if you wanted to turn it on and off by time of day? Say you only wanted WiFi calling enabled during rush hour, when your cell tower was completely overloaded? There’s a Tasker plugin for that now.
I’ll point out that I’m playing with this on an unsupported device, and it obviously doesn’t work right for me. It’s only officially supported on on T-Mobile, but the hope is that the plugin developer will get some more carrier and device love soon enough, as this is a very useful tool.
The action for the task is pretty simple and can turn WiFi calling on, off, toggle it, choose WiFi preferred, cell preferred, or never use the cell network.
I really wish this were compatible with Sprint, since from 4:00-6:00 p.m. my cell tower is a wasteland as 100,000 people crawl by it in rush hour traffic, but hopefully some day. For you T-Mobile folks, it’s Tasker control time.
It should be noted that on some devices you will need root access in order to modify the WiFi calling state. Your device will vary.
You can head over to the plugin development thread at XDA and download the plugin, or if you just want a widget that switches it on or off there’s one available for download, too.
