Expro Group International Selects Global Telecom & Technology
To Provide Connectivity Solutions In Africa


GTT Provides Critical Link Into Remote Areas Using VSAT Technology


LONDON and MCLEAN, Va., September 13, 2007 – Global Telecom & Technology, Inc.
(“GTT”), (OTCBB: GTLT), a global Multi-Network Operator (MNO), announced today that Expro
International Group PLC (EXR.L) has selected GTT to provide connectivity solutions to several of
its offices in Nigeria and Angola.

The multi-year contract calls for GTT to provide an integrated telecom solution designed around
satellite-based Very Small Aperture Terminal (VSAT) technology. The office locations serviced
by the contract are in remote parts of Africa that lack viable fixed-line telecommunication
solutions. Expro, a leading global oilfield service company, has over 4,000 employees located in
more than 50 countries worldwide.

“What attracted us to GTT was its business model,” said Martin Ogden, Group IT head of
infrastructure and operations support, Expro. “GTT is not fixed to any one carrier or any one
service provider, which enables it to source bandwidth and network connectivity from the most
appropriate carrier in order to obtain the best possible deal for its customers.”

GTT’s customized network solution will provide Expro’s Nigerian and Angolan staff offices with
the same direct access to all core systems and services available to other Expro sites, as well as
full connectivity to all corporate servers and applications. In addition to new and unique
connectivity into the region, GTT also streamlined the implementation process by providing a full
turn-key offering which included procurement of the satellite equipment on Expro’s behalf.

Commenting on its ability to provide such a unique end-to-end solution, Richard D. Calder, Jr.,
president and CEO, GTT, said, “GTT has significant knowledge and expertise in delivering
services into remote regions around the world, including Africa. We have focused on managing
strong working relationships with satellite service providers and local incumbent telcos to ensure
effective service provisioning and management. This is a core capability for GTT. For Expro, we
were able to offer a true turn-key solution – from designing and provisioning the network, to
procuring and deploying the equipment, to maintaining and supporting ongoing service. This turn-
key service combined with a single service level agreement is a key differentiator for GTT.”
