I subscribe to Ting and I'm happy with it. But, while very good, it's far from unique. I came in from another Sprint MVNO that was very good but slipping in value proposition. An MVNO is almost by nature a precarious thing. Major telecom? It's a subsidiary of Tucows, which will to me be forever be linked to '90s shareware downloads, its listing is basically an accident of the dotcom bubble, and it has a market cap of < $300 million. I'm guessing their domain name line easily rivals Ting in value. Healthy in its niche, but no major force. By comparison, Frontier, a smaller RBOC, is worth $5.6B, frigging T-Mobile is worth $9.5B.

Sprint is losing $2 billion a year. No Sprint MVNO is sustainable.
