Yes, simultaneous voice calling and 3G data work on the HTC EVO 4G LTE
Two weeks ago when I told you to ask me anything about the HTC EVO 4G LTE, I got some really good questions. I tried to answer some of the best ones (here, here, here, and here), but I realize that there are some pretty good questions that are still unanswered. So, if your question was one of the unlucky ones not to get a formal answer from me yet, don't worry: as we continue to cover all things EVO, we'll touch upon some of those important issues that you brought up in greater depth, such as multi-tasking, unlocking, more in-depth battery testing, etc. I want to devote entire articles to some of these topics, as they're just too big to answer in a quick Q&A format.
That being said, several of you asked me about whether or not the rumors of simultaneous voice calling and 3G data were true. I'm happy to announce that they are!
To make sure that everything was set up just right, I double- and triple-checked that LTE and WiFi were both off before making a call and doing this speed test. Unlike all previous EVOs, which drop the 3G data connection (and the icon in the notification bar), the EVO 4G LTE keeps a steady 3G connection. Data speeds also don't seem to suffer one bit while on a call.
I've already mentioned that connectivity on the EVO 4G LTE is awesome in general; it usually picks up a stronger signal than my EVO 3D on both the cellular network or any surrounding WiFi networks. Additionally, mobile data speeds are consistently 300-500kbps faster on the EVO 4G LTE than on the EVO 3D, even when the devices are side-by-side.
This is one little-touted but much-appreciated feature on the EVO 4G LTE, and I hope Sprint and HTC will continue the trend in any and all future CDMA-compatible EVO devices.
