Every price, plan limit, trial, integration, language count and compliance statement on this site was read from the software company's own website. We link the source next to each product. The last full check was October 22, 2026.
What we do and do not do
- We record what each company publishes. If a company's own pages disagree, we show both or leave the detail out.
- If a company does not publish something (for example an overage rate), we say "Not published" instead of estimating it.
- We have not run test calls on these products, so we do not score voice quality.
- Cost examples use list prices only and show the math. They assume a 3-minute average call unless stated, and the cost calculator uses the same formulas, checked by automated tests on every build.
- Laws are cited to the statute or the government agency that publishes the rule.
Advertising disclosure
Some links on this site may be affiliate links, which means we may earn a commission if you sign up, at no cost to you. Commissions never change what we publish: products are listed by published starting price, and every fact links to its source.
