Vietnam's mobile market has around 130 million subscriptions, dominated by military-backed Viettel (market leader), state-owned VNPT's Vinaphone, and MobiFone, with smaller players like Vietnamobile holding minor shares. Prepaid subscribers form the majority, and USSD is widely used for balance checks, data pack purchases, and short-term bundle subscriptions.
