Scoring Methodology & Data Provenance
We reject paid placements and sponsored bias. All carrier comparisons are driven by deterministic TypeScript algorithms, 24-month TCO amortization models, and SHA-256 cryptographic snapshot archives.
Zero Paid Placements
No carrier can purchase top placements, badges, or biased verdicts. All rankings are 100% mathematical.
5-Round Deterministic Engine
Plans are evaluated across 5 rounds: 24-Month Cost, Network & Speed, FUP Safety Floor, Roaming & Add-ons, and Support Channels.
SHA-256 Provenance & Snapshots
Every tariff claim is backed by immutable HTML snapshots, CRTC tariff filings, and cryptographic SHA-256 hashes.
Sharp at Clause, Neutral at Entity
We critique specific contract traps ($20/GB overage, price jumps) while maintaining strict corporate neutrality under Competition Act §74.01.
The Mathematical Formula & 5-Round Scoring Weights
Where P_base is regular base price, D_autopay is pre-authorized debit discount (requiring bank account link), F_sim is one-time SIM card fee, and F_activation is connection fee. Contact: [email protected].
| Dimension | Evaluation Metric | Weight | Deterministic Criterion |
|---|---|---|---|
| 1. 24-Month True TCO | Amortized lifecycle cost in integer cents | 40% | Lower 24-month total cost wins decisive margin. |
| 2. FUP Safety Floor | Throttled data speed vs overage penalty | 20% | 256–512kbps unlimited wins over $20/GB hard overage. |
| 3. Network & Speed Tier | Physical host RAN & throttle cap | 15% | 5G+ (2Gbps) > 5G (250Mbps) > 4G (150Mbps). |
| 4. Roaming Scope | Inclusive regions vs $16/day pass | 15% | Included US/Mexico roaming wins over pay-per-use daily pass. |
| 5. Support Channels | Phone & store availability vs self-serve | 10% | Audits human assistance value for different demographic cohorts. |
Frequently Asked Questions & Policy Gotchas
Can a carrier pay to get a higher ranking or positive verdict on Celluplan? ▼
No. Celluplan operates under a strict zero-paid-placement policy. All comparisons, winner margins, and scorecards are deterministically calculated by open-source domain logic in TypeScript. No advertiser or affiliate partner can influence scoring.
How are 24-month total costs (TCO) calculated? ▼
Our math includes base monthly rates, autopay requirements, mandatory connection/activation fees, temporary promotional drop-offs, and estimated overage risks. We never quote temporary promo teaser rates without full 24-month amortization.
How do you verify data accuracy and protect against carrier disputes? ▼
Every captured rate and contract clause is archived with raw HTML snapshots and cryptographic SHA-256 hashes. If a carrier modifies a plan, our versioned ingestion pipeline records the exact timestamp.
