The Airave works well, when it works. You have to have a reliable ISP with low latencies.
The one thing it does well is stopping your battery die. When you get home and your phone is in your pocket, the battery does not die as the phone isn't searching hard for a signal. <---- you guys do not understand how good this is.
T-Mobile's Wifi calling does NOT stop your battery running down, even if you're on wifi, the phone is continually searching for a T-Mobile signal. The Airave works better than this.
The Airave's EVDO data speeds are a little better than the real Sprint EVDO speeds, usually get around 0.2 Mbps when connected to the Airave.
It works really well for txt messages, SMS/MMS.
