Four Vietnamese mobile network operators have signed an agreement to share over 1,200 base transceiver stations (BTS). According to the Ministry of Communications (MIC), the move will enable Viettel, VNPT-Vinaphone, MobiFone and GTel Mobile to reduce deployment infrastructure costs and also promote the rollout of 5G networks. In November 2019 the MIC published Directive No. 52/CT-BTTTT on the sharing of passive technical telecoms infrastructure among telecoms operators, and in May VNPT-Vinaphone and MobiFone agreed to share infrastructure at 700 locations. Vietnam currently has around 261,000 BTS across the country, of which 110,000 are 4G LTE base stations.
