Case Study: G-Mobile grows MVNO revenue 20% and customer base 8X with PortaOne PortaSwitch

G-Mobile - Customer Case Study

G-Mobile, a telecom operator in Armenia, faced the challenge of launching and growing its HelloSIM MVNO brand affordably. The high cost and inflexibility of traditional core network infrastructure from major vendors made it difficult to achieve low operational costs and the rapid service deployment needed to compete. To solve this, they chose PortaOne and implemented its PortaBilling platform for business support and real-time charging.

By combining its own custom-built core network with PortaBilling’s open architecture, G-Mobile significantly lowered its operational costs. PortaOne’s solution enabled advanced call routing that cut expenses, allowing HelloSIM to offer highly competitive rates. This resulted in an 800% growth in its customer base in one year and allowed G-Mobile to expand its own business by becoming an MVNE for other brands.
