This isn't in the right section, but the first things to check would be if the data connection settings are correct. I don't have an Evo in front of me, but check in Settings / More... and there should be some stuff there to make sure that CDMA/LTE is enabled or if you just want 3g, do CDMA/EVDO (I'd switch between the 2 to see if it makes any difference). Seems like this is not a totally uncommon issue with these phones. Some people just had issues with the towers updating (even though your other phones work ok, every phone is different and use different radios so not exactly apples to apples), sometimes it was just needing reset (either via factory data or ##72786# which will reset network stuff and redo the Hands Free Activation and update the PRL). That's usually the other thing to check : Make sure the Profile and PRL updates are done. Unfortunately, some users report doing all of that and still never resolving. Good luck!
