This seems like a very nice option for people with bandwidth needs that don’t fit in the tiny caps most cell phone providers put on plans. For $50/month you get unlimited data @5 Mps in the USA. You can get small increases to the speed by buying data in bite sized chunks (1Gb for $14 or $99 for 10GB, which doesn’t expire).
The bite sized chunks mainly make sense if you don’t have high data needs for the hotspot – but want it occasionally (and perhaps as backup for your primary connection). The $50/month offer is limited to 3 devices connecting at a time, compared to 8 for the other option.
The device itself costs $149. The device has up to 8 hours of battery life and over 220 hours of standby time.
Currently the devices use Sprint’s Nationwide 4G LTE network, with fallback to 3G CDMA. It seems like a nice option for travelers to me.
