A difficult-to-pronounce company - Zer01 has today announced its plan to offer unlimited voice, text, and data for a monthly price with no contract or credit check.

Zer01 has announced that its smartphone software facilitates providing unlimited domestic VoIP calls and unlimited data for a pre-release price of $69.95 per month. Paying an extra $10 a month, the users can enjoy making unlimited international calls to 40 countries.

Zer01 has told that Windows Mobile 6 is need at launch to install Zer01's software. It has told that as a mobile virtual network operator (MVNO), ituses AT&T's existing GSM cellular network, repurchasing service.

Zer01 has claimed that it has avoided the typical limitations carriers impose on MVNOs, including paying a metered rate for service, by applying a VPN tunnel to carry VoIP calls from handsets over cellular backhaul (from GPRS and EDGE up to full HSPA 3G) to its own IP backbone.

AT&T has not yet offered ant official comment on its MVNO relationship with Zer01 or its standard process for MVNO partners.

According to Zer01 CEO Ben Piilani, "the company has developed proprietary algorithms and defragmentation engines to handle latency issues and ensure that the VoIP has a high quality of service, even over an EDGE or GPRS connection". "We look at ourselves as a new carrier, and this is definitely a disruptive technology," Piilani has said.

Zer01 has announced to launch its calling service in April with a private beta. Zer01 stated that it will provide additional details at this year's CTIA trade show on April 1, one of the biggest events of the cellular industry.
