Verizon Wireless is the largest carrier in the U.S. with over 115 million subscribers. China Unicom is the second largest carrier in China, but it makes Verizon look almost puny by comparison. China Unicom has over 300 million mobile subscribers, which easily dwarfs Verizon, but that's to be expected since there are only about 320 million people living in the U.S.
Both carriers were courteous in their announcements. Verizon said of Ubuntu that it has "the ability to bring new and exciting features to developers and ultimately, customers.” China Unicom says that Ubuntu can be "an exciting new platform for the Chinese market, offering a brand new user experience that balances user simplicity with operator requirements." Even more interesting is that there is talk of China Unicom having exclusivity in bringing Ubuntu Touch devices to the Chinese market.
Canonical's Pat McGowan told us that a big reason for creating the Carrier Advisory Group is to find ways of providing "differentiation without fragmentation". And, Pat said that Canonical would stop accepting new members at the end of July.
