Verizon Wireless, the North American wireless carrier, is now seeking to sign its first international roaming agreement. The service is for customers who travel overseas seeking to retain the world's fastest wireless service during their trip.

According to a top executive of the US mobile provider, Verizon already has 200 existing partnerships with overseas operators for its third generation service but there are no existing agreements for the fourth generation Long Term Evolution (LTE) data services. The LTE was made available in the United States back in 2010.

Chief Technology Officer for Verizon Wireless Nicola Palmer said that the roaming agreements have not yet been signed because many networks are in the process of upgrading their systems. Many other countries have yet to sell of their wireless systems in order to upgrade to LTE services.

There is no inkling as to the first partner but it is expected that LTE roaming is projected to be available in countries such as Canada by 2014.
