Alliances are forming between global mobile phone operators that are allowing subscribers to use their cellphones in just about any country. Taking the next step, new agreements are being struck to bring WiFi accessibility to cover a wide range throughout the globe. This is basically what the Wireless Broadband Alliance is all about.

In one example, Telecom Italia and NTT Communications of Japan have agreed to allow their respective customers to use each other's hotspot while being billed directly on their domestic phone bill.
 
However, individual members within the Wireless Broadband Alliance have to sign bilateral agreements to begin their partnership. Depending on the deal, customers can either be billed directly on their domestic phone bill or they can pay a monthly fee though a website. In other words, if a company decides to go it alone and offer access to anyone from anywhere, they have to make sure they have a partner, or there won't be much of a chance to build a revenue stream.
