China Mobile International and US carrier Clearwire have signed a non-binding memorandum of understanding (MOU) for international roaming between China and the United States using TD-LTE. Under the MOU, China Mobile and Clearwire plan to collaborate on business and technical aspects of their respective operations to define and institute the process necessary to support international roaming and to ensure the operators' systems and devices are able to support roaming. 

The companies also expect this agreement to serve as a blueprint for future roaming agreements with other members of the Global TD-LTE Initiative (GTI) of which China Mobile and Clearwire are founding members.

China Mobile and Clearwire are developing TD-LTE networks in their respective domestic markets. Through mutual collaboration, the companies will provide their customers with 4G roaming capability and help 4G services to follow the same global pattern towards international accessibility as other wireless technology. The companies expect the spectrum in the 2.3GHz to 2.7GHz range which will be used in their TD-LTE network deployment will make up one of the most widely deployed 4G configurations in the world.
