Coverage: Guam is a single-operator market (GTA Wireless). All 5 providers share the same infrastructure. Coverage scores compress because no provider has a carrier advantage. The dimension effectively neutralizes.
Network: Guam runs on 4G LTE. Since all providers route through the same infrastructure, network scores track the carrier tier, not the provider. Pricing: plans start at $7.99 (1GB), $7.99/GB floor rate. Unlimited daily data from $14.19/day shifts the pricing calculus for heavy users. Overall spread: 0.49 points between #1 (HelloRoam) and #4 (Nomad). Provider selection matters significantly in Guam.
