What the rubric scores
The rubric ranked 7 eSIM plans from 5 providers for Luxembourg on five dimensions: Coverage (25%), Pricing (25%), Network tier (20%), App features (15%), Support access (15%). Each provider takes a 1-5 mark per dimension, and the weighted total is doubled to give the /10 display score.
Where the inputs come from
Scores for Luxembourg 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.

Luxembourg Network Landscape
Luxembourg has 3 mobile networks: Tango (5G), Orange (5G), POST (5G). POST delivers the strongest coverage combination. All 5 providers route through these carriers.
Carrier Partnerships
Luxembourg operates 3 mobile networks: Tango (5G), Orange (5G), POST (5G). POST serves as the primary routing partner for travel eSIMs in this market. All five ranked providers maintain routing agreements with POST. Some providers additionally route through Orange as a fallback when POST's signal weakens.
POST publishes 5G across Luxembourg, and every ranked provider attaches to it rather than to a network of its own. With 3 networks accepting eSIM roaming, Luxembourg offers strong carrier diversity. Signal handoffs between Tango, Orange, and POST keep connections stable across geographic boundaries.
Carrier selection in Luxembourg is largely predetermined by POST's dominant roaming agreements. Providers compete on plan structure, pricing, and service quality rather than network access. Coverage scores follow the published partner list rather than anything measured on the ground.
