Vietnamese mobile network operators Viettel, VNPT, MobiFone, Vietnammobile, Local, Reddi, Itel, and GMobile will make a concerted effort to stop spam calls under an agreement signed in Hanoi on August 29.
Deputy Minister of Information and Communications Phan Tam urged mobile network operators to further simplify procedures for mobile number portability (MNP) services to create convenience for users to switch networks.
Four mobile network operators of Viettel, Vinaphone, MobiFone and Gtel signed an agreement in Hanoi on June 10 to share about 1,200 base transceiver stations (BTS).
MobiFone, one of Vietnam’s three largest mobile network operators, has reported a year-on-year decline of 42 percent in post-tax profit in the second quarter of this year, falling to 947 billion VND (41 million USD).
