Where the inputs come from
Scores for Sri Lanka use the published weighted formula: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), and Support access (15%). Each dimension receives a raw score from 1 to 5. The composite multiplies by 2 for a 0-10 display scale. Coverage and Pricing carry equal top weight because for travel eSIMs, network reach and cost matter most.
Country-specific adjustments for Sri Lanka: Single-carrier markets like Sri Lanka receive a ceiling of 4.0/5 on Coverage, since no failover redundancy exists. Unlimited plan availability in Sri Lanka adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates.
