Lokdeep Singh, vice president of engineering at WorldCell.

“Wireless operators understand that people depend on their mobile phones just as much when they are traveling as they do when they are in their home town on their home networks. But just as much as they depend on their phones, they also expect them to simply work when they turn them on, which is why inter-standard roaming is an essential service for wireless operators to provide their customers. WorldCell evaluated and tested a great deal of technology before determining which to integrate with our Inter-Standard Roaming service. We found that Aicent’s CRX and GRX roaming eXchange services were some of the most scalable and reliable on the market.”
