What We Tested
We ranked 5 eSIM plans from 5 providers for Swaziland across five dimensions: Coverage (25%), Pricing (25%), Speed (20%), App Quality (15%), Support (15%). Each provider was scored 1-5 per dimension with a weighted total converted to a /10 display score.
How We Scored
Scores for Swaziland use our standard weighted formula: Coverage (25%), Pricing (25%), Speed (20%), App quality (15%), and Support (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 Swaziland: Single-carrier markets like Swaziland receive a ceiling of 4.0/5 on Coverage, since no failover redundancy exists. Unlimited plan availability in Swaziland adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates. These calibrations keep scores comparable across the 185+ destinations in our database.
The scoring spread across 5 providers for Swaziland is 1.5 points (HelloRoam at 9.5/10 down to Nomad at 8.0/10). A spread under 1.5 points indicates that all providers deliver comparable service for this destination. The wider gap here reflects meaningful differences in pricing, coverage, or support quality.
