Methodology · Sources · Limits
How this site gets its data, and what it does not guarantee — stated honestly.
Sources
We normalize price numbers (facts) from each provider’s public pricing pages. We do not copy page text or layout. Each rate shows its source link and collection date. Telnyx uses a machine-readable ledger (pricing.md); the others use public rate pages.

What we do NOT guarantee (important)
- Listed rates may not be flat. ‘from’ (~) is the lowest in-country network rate; actual cost depends on the destination carrier.
- Billed ≠ listed. US 10DLC carrier fees & registration, India DLT, and markets like Nigeria (20x+ carrier spread) add real cost.
- $0 may not be free. Some rates are placeholders requiring a separate rate-deck lookup.
- Freshness. Prices change often. Check each row’s collection date and verify on the official page before buying.
- Neutrality. No affiliation or sponsorship with any provider.
