Zer01 hit the market with a lot of hoopla and a lot of talk about unlimited everything for only $79.99 per month. However, they have yet to put any of their services into action! Zer01 is an MVNO or MVNE, and they say that they can offer cheap unlimited service by the 3G GSM cellular data network of a national partner, which they will resell. I imagine the national partner is AT&T Wireless since AT&T Wireless is the largest GSM carrier in the US. Voice services would be delivered as data using VoIP. Zer01 launched with unlimited voice, text, and data plans for $79.95 a month - including tethering your laptops all you want, and with no contract. The problem is: there is no evidence that this service actually exists.
