GRX (GPRS Roaming Exchange) in Mobile Networks
GRX refers to (GPRS Roaming Exchange). It is a dedicated IP network infrastructure that facilitates the exchange of roaming-related data between different mobile network operators (MNOs) around the world.
It acts as a centralized hub, interconnecting multiple MNOs and enabling them to exchange roaming-related data without the need for direct bilateral connections. This simplifies the roaming setup and management process for the MNOs.
GRX infrastructure is typically operated and maintained by specialized service providers, known as 'GRX providers' or 'roaming hubs'.
