Virtual carriers are only as healthy as the companies that provide their services -- and Australia's Kogan Mobile is learning this the hard way. Its wholesale cellular partner ispONE has just entered administration following a contract dispute with Telstra, ending all its deals for prepaid 3G services and leaving Kogan Mobile no choice but to wind down. Customers have already lost the ability to add or replenish services; they'll have up to 60 days after a Telstra notice to use any credit they have left, and 180 days to port their numbers elsewhere. While Kogan's shutdown may only affect about 100,000 people, it still represents an unfortunate loss of competition in a country with few major providers.
