As CTIA prepares for this year's show on March 23, Zer01's Web site has disappeared. The site recently began redirecting visitors to Google.com.

Zer01 introduced itself at CTIA in 2009 with great fanfare. It promised a flat-rate, no-contract, completely unlimited cell phone service. So interesting was the concept that mainstream media and the trade press lauded the new company.

Zer01 then with a multilevel marketing company called Global Verge, and the two companies began recruiting salespeople who paid a monthly fee to be part of a sales program. However, no mobile service from Zer01 ever materialized. Salespeople were promised payment based on how many other salespeople they signed up to the program, although few appear to have received any payment.

Global Verge and Zer01 parted ways. But as late as the fall CTIA show in October 2009, Zer01's CEO Ben Piilani was still promising to launch the mobile service during the MobileFocus event. Zer01 is not listed as a participant in the forthcoming MobileFocus event at the CTIA conference in less than two weeks.

As of Friday, the Zer01 Web site redirects all traffic to Google.com. of the site show that it was still displaying Zer01 content as recently as March 2.
