Conversely, GSM networks provide reliable infrastructure for Mobile Money, extending connectivity and financial inclusion, especially in regions with limited traditional banking infrastructure. Their synergy revolutionizes financial transactions, empowers the unbanked, and drives economic growth throughout the digital economy.
