What's a Karma Go? In layman's terms, the Karma is a portable cellular data modem/hotspot. It looks slick and gets up to 8 devices simultaneously connected. The first model, powered by WiMax, launched two years ago in 80 American cities. It was met with enough enthusiasm that the follow-up arrived this September.
A product of a one year and a half cooperation between Karma Mobile and Sprint, the Karma Go is the LTE Cat. 3-enabled sequel. Karma's philosophy is that Wi-Fi should never be something you have to hunt for. Thus, it made Wi-Fi follow you everywhere you go. The Karma Go is streamlined to the point you forget about its existence and simply use the Internet, which you can do for up to five hours on a single charge. It's an inconspicuous white rectangle with smooth edges, three signal strength LEDs, and a microUSB port. Data speeds reach up to 25Mbps download and 23Mbps uplink on LTE, and up to 3.1Mbps download and 5Mbps uplink on CDMA (which it automatically reverts to when there's no LTE coverage). Wi-Fi connectivity is established on the 802.11b/g/n 2.4Ggz standard. The whole gizmo weights just 2.3
ounces / 56 grams.
Now, what about the business end of things? Karma uses Sprint's nation-wide LTE network to offer a flexible, contract-less data plan. The device itself costs $150. Users pay $14 per gigabyte - that's all there's to it. There are no overages or line access fees. The traffic never expires. Buy and use data when you need it, just like you're dealing with fuel for your car. Users that share their connections with strangers receive discounts. We have to say, we like the concept. But we'll leave it to you to make up your mind whether Karma has a better offer than any of the Big Four US carriers for you.
