Karma, an MVNO that operates on Sprint's network, has canned its unlimited service plan called Neverstop. The company said the plan was simply not feasible. "We tried to make Neverstop work by regulating the number of devices you could connect, limiting speeds to 5Mbps, and most recently, capping usage at 15GB per month," said Karma in a blog post. "None of these changes made Neverstop sustainable at $50 a month, and most importantly, they all degraded the experience for customers. The time isn't right for this service. We like to dream big, but this time we went too big." Karma launched the never stop service for its Go LTE mobile hotspot three months ago. Customers quickly abused the unlimited plan, forcing Karma to use throttling and other techniques to discourage overuse. The measures weren't enough. Karma is replacing Neverstop with a series of plans called Pulse that range from $40 per month for 5 GB to $140 per month for 20 GB. Karma subscribers can upgrade or downgrade their plans at any time, and can add extra data for $15 per 1GB.
