Data sources
A benchmark is only as honest as its inputs. Here is every source that feeds a score, and which dimension it informs. Each individual score on the site also carries its own visible source and date — see the methodology for how they combine.
| Source | Feeds | What it provides |
|---|---|---|

| Provider plan catalogs | Pricing Value, Plan Flexibility | Published rate cards and plan pages, normalized to cost per gigabyte. |
| Apple App Store | App Quality | Recent public user reviews and ratings for each provider iOS app. |
| Google Play Store | App Quality | Recent public user reviews and ratings for each provider Android app. |
| Trustpilot | App Quality (supporting) | Supplementary public review signal, used as a cross-check only. |
| Provider terms of service | Fair Use & Refunds, Hotspot & Tethering | Throttle thresholds, refund rules, and tethering policies read from the official ToS. |
| Standardized support tests | Customer Support | Identical queries sent to every provider each quarter via live chat and email; response time measured. |
| Mobile network (MNO) mapping | 5G Access | Underlying partner-network mapping used to determine genuine 5G availability per country. |
