AT&T has selected Ericsson to provide testing and verification for devices within its Global SIM Program. Ericsson will test the performance for each manufacturer's device to ensure the devices are compatible with regulatory and international carrier requirements and networks. Device verification and carrier certifications are crucial to robust, optimized device performance across the extensive, standards-based mobile broadband infrastructure that Ericsson delivers globally.

According to the agreement, AT&T's global SIM devices will be verified and tested by Ericsson prior to launch in Ericsson labs throughout the world. As the global leader in mobile networks, Ericsson is able to help operators like AT&T secure the best customer experience by helping them make devices more network friendly, as well as making networks more device friendly. Through its global device labs, Ericsson is able to ensure maximum performance for both device manufacturers and network operators.

In 2012 it launched the innovative AT&T Global SIM program, which is in line with its strategic intent to expand its international business and take its vision for connected devices to the next level.
