What We Tested

We ranked 7 eSIM plans from 5 providers for Luxembourg 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 Luxembourg 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 Luxembourg: Unlimited plan availability in Luxembourg adjusts the Pricing dimension to weight per-day unlimited rates alongside per-GB fixed rates. Widespread 5G in Luxembourg adds a 0.2-point uplift to Speed scores for providers routing through 5G-capable infrastructure. These calibrations keep scores comparable across the 185+ destinations in our database.

The scoring spread across 5 providers for Luxembourg 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.
