Speed Comparison
Viettel leads Vietnam on every speed category. Its 226.27 Mbps 5G download and 82 Mbps 4G download place it 3rd globally. MobiFone’s mobile speeds are decent for urban areas but lag behind Viettel by a significant margin.
MobiFone’s 5G rollout trails both Viettel and VinaPhone. The network is smaller, and independent speed tests consistently show MobiFone behind Vietnam’s top two operators.
Viettel also offers FTTH fiber broadband. MobiFone focuses on mobile-only service. Users who want bundled home internet and mobile should look at Viettel or VNPT.

Coverage
Viettel covers all 63 Vietnamese provinces with strong 4G and growing 5G. Its military-backed infrastructure reaches remote mountain communities, border areas, and islands. No other Vietnamese operator matches Viettel’s rural coverage.
MobiFone covers all major cities well. Hanoi, Ho Chi Minh City, Da Nang, and provincial capitals have adequate MobiFone signal. Coverage drops faster than Viettel in rural and remote areas.
For users staying in major Vietnamese cities, both operators work. For travelers and rural users, Viettel is the only reliable choice.
Which Should You Choose?
Viettel is the clear choice for most Vietnamese mobile users. Faster speeds, wider coverage, fiber broadband option, and competitive pricing make Viettel hard to beat. The global #3 speed ranking speaks for itself.
MobiFone may suit budget users in cities who find a promotional deal. MobiFone occasionally offers competitive short-term pricing to attract subscribers. For long-term value, Viettel delivers more.
Compare VinaPhone as an alternative. VinaPhone leads on 4G upload speed (38 Mbps) and ranks 2nd globally for 5G performance.
Summary
Viettel dominates Vietnam’s mobile market with 110 million subscribers and world-class speeds. MobiFone is a smaller third operator that cannot match Viettel on speed, coverage, or service breadth. For most users, Viettel is the better network.
