Smaller Subscriber Base Than Viettel: VinaPhone holds 17.49% market share compared to Viettel's 57.6%, limiting network investment scale relative to Vietnam's dominant operator, according to Wikipedia telecom data 2023.
5G Coverage Still Expanding Beyond Core Districts: As of early 2025, VinaPhone targets tripling 5G geographic coverage to reach 99% population coverage by 2030; rural sub-district and hamlet-level 5G coverage remains incomplete in 2026, according to VNPT February 2025.
4G Speed Trails 5G Rollout Priorities: VinaPhone's median 4G download speed of 53.24 Mbps (Ookla Q2–Q3 2023) is strong but reflects Q2–Q3 2023 benchmarks; as network investment shifts toward 5G densification, 4G performance data in rural areas requires updated independent measurement.
