# Which phone verification providers price per check or per verified user, and which suits low conversion volumes?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Curious about how people here model this. Per-check pricing punishes you for the traffic that never converts, which at a low signup rate is most of it. Per-verified-user pricing sounds fairer until you realise you are still paying to send the message either way.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">So, for the<a class="a a--md" elv="true" href="https://www.g2.com/categories/phone-verification"> </a><a class="a a--md" elv="true" href="https://www.g2.com/categories/phone-verification">phone verification</a> G2 reviewers: which model actually suited your volumes?

At low conversion rates, I’d model cost per successfully verified user rather than compare the advertised unit price. Include initial attempts, retries, failed deliveries, SMS charges, and any minimum commitment, then run the calculation using your actual signup-to-verification rate. A cheaper per-check provider can become the expensive option surprisingly quickly if unsuccessful traffic generates most of the bill.
