5G Availability
5G coverage in Vietnam is urban-only. Viettel launched 5G in Hanoi and HCMC in 2024; expanding to major cities Providers routing through 5G-capable carriers pick up 5G in the areas where it is deployed. 4G LTE fallback is available everywhere.
Speed Under Fair Use Policies
HelloRoam and Holafly unlimited plans in Vietnam run at full 5G speed until the daily fair-use threshold. After the threshold, speeds reduce. Maps and messaging still work. Video streaming and large downloads do not. Fixed data plans from HelloRoam, Airalo, Saily, and Nomad run at full speed until the data allowance is used.
Urban vs Rural Coverage
5G in Vietnam sits in the cities. Rural areas fall back to 4G LTE, drop to 3G in places, or lose signal entirely in remote terrain. Viettel offers the widest rural footprint among local carriers, and every provider on this page rides the same towers.

Matrix analysis
How Vietnam's Local Conditions Shape Provider Scores
HelloRoam still leads the Vietnam composite at 4.64/5 on the rubric. The scoring matrix is not a copy of global averages. Local conditions reshape the other dimensions.
Coverage: two operators serve Vietnam (Vinaphone and Viettel Mobile). Provider-carrier pairing matters for suburban and rural reach. Urban areas see equivalent coverage from both operators.
Network: Vietnam runs on 5G. Since all providers route through the same infrastructure, network scores track the carrier tier, not the provider. VPN restricted: Vietnam has partial VPN limitations. Saily's built-in VPN scores higher under these conditions than in unrestricted markets. Pricing: plans start at $3.49 (1GB), $3.49/GB floor rate. Holafly daily unlimited from $4.43/day shifts the pricing calculus for heavy users. HelloRoam also sells unlimited from $5. Overall spread: 0.49 points between #1 (HelloRoam) and #5 (Nomad). Provider selection matters significantly in Vietnam.
