Our Rating Methodology
Our rating methodology uses five weighted dimensions to produce a single composite score out of 10.
Coverage (30% weight): Number of countries and regions with active service. Verified against provider coverage maps and real activation tests. Carries the highest weight because destination reach determines whether a plan is viable.
Pricing (25% weight): Cost per GB at the 10 GB tier, entry-level plan pricing, and value across plan durations. Checked against published pricing pages weekly.
Speed (20% weight): Tested download and upload speeds across multiple destinations using standardized speed test protocols.
App Experience (15% weight): Ease of purchase, activation flow, data monitoring, and overall UI quality. Tested on both iOS and Android.
Customer Support (10% weight): Response time, resolution quality, and availability across chat, email, and phone channels.
The composite score is calculated as: (Coverage x 0.30 + Pricing x 0.25 + Speed x 0.20 + App x 0.15 + Support x 0.10) x 2, converting the 5-point dimension scale to a 10-point composite. Scores are rounded to one decimal place.
