Matrix analysis
How Vietnam's Local Conditions Shape Provider Scores
The Vietnam scoring matrix is not a copy of global averages. Local conditions reshape provider performance.
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. Unlimited daily data from $4.43/day shifts the pricing calculus for heavy users. Overall spread: 0.49 points between #1 (HelloRoam) and #4 (Nomad). Provider selection matters significantly in Vietnam.
