About cellt

cellt.net is an independent, ad-free comparison site for US cell phone plans. We aggregate plan data from the carriers' own published pages, score plans against your usage profile, and factor in coverage at your address using public FCC data.

What makes us different

• Independent. We don't take payment from carriers in exchange for ranking, placement, or favorable copy. There are no sponsored picks.
• Ad-free. No display ads, no AdSense, no affiliate codes appended to outbound carrier links. We don't currently earn commissions from any carrier (see the disclosure).
• Coverage-aware. Most plan-comparison sites compare prices and features only. We layer in ZIP-level coverage from the public FCC Broadband Data Collection so a "best plan" recommendation reflects the network actually working at your address.
• Editorial picks are human. Our best-plan recommendations are written by people, with reasoning. The algorithm filters and scores; the editorial layer says "this one fits this person."
• No paywalls, no signup walls, no email capture. Every page is fully readable to a first-time visitor.

How content gets made

The site uses AI to draft plan-page summaries, glossary entries, and city/state coverage notes. Every AI-drafted change to plan or coverage data passes through human review at /admin/ingest before it goes live. Editorial content (guides, best-of picks, page intros) is human-written end-to-end. We disclose this here because Google's helpful-content guidelines (and basic honesty) ask us to.

How the scoring works

Read the methodology page for the full breakdown. Short version: we apply hard filters first (a plan that doesn't include hotspot is excluded if you said you need hotspot, not down-ranked), then score the remaining plans on a fit metric that combines price, data, and (when a ZIP is provided) coverage strength at your address.

What we cover

23 active US carriers (the four MNOs — Verizon, T-Mobile, AT&T, Dish — plus the major MVNOs riding them). 31 active plans with full data. 35 phone manuals with quick-reference Q&As. 39 glossary entries for the underlying terminology. 30 state pages and 33 metro-level pages with region-specific carrier notes. The full surface is browseable on the sitemap.

Who runs cellt
