Connecting to Wi-Fi hotspots via SIM authentication sets the stage for future business models based on Hotspot 2.0, Passpoint and Next Generation Hotspots. AT&T granted roaming customers on certain plans 1GB of free Wi-Fi service at select AT&T International Wi-Fi hotspots, and because it uses Accuris Networks' AccuRoam technology, those hotspots can be accessed seamlessly using SIM-based credentials. This obviates the need for a user to launch a client or enter a username and password to gain Wi-Fi hotspot access.

“We see this as the beginning of a big trend of mobile operators leveraging Wi-Fi not just for domestic offload to ease congestion but in a roaming scenario as well to give better roaming rates to their end users,” said David Reeder, Accuris’ VP of sales and business development.
