Beyond the unit price
A cheap send is not cheap when it fails, attracts fraud, or adds another platform fee.
Your wallet is charged after delivery is confirmed. Failed and undelivered OTP messages do not become wasted verification spend.
Rate limits by phone number, IP address, and number prefix help reduce automated abuse before it drains your budget.
Send, verify, and check status through a compact server-side API without adopting a full multichannel communications stack.
Authentication templates travel through the official WhatsApp Business Platform with delivery events and message logs.
Migration plan
Start with one authentication flow, one market, and a measurable success target.
Divide total verification spend by successful deliveries. Include provider fees, carrier charges, failed attempts, and fraud.
Route eligible US and UK users to WhatsApp first while preserving SMS or another recovery channel for exceptions.
Measure delivery, completion, support burden, fraud, and cost per successful verification before moving more traffic.
Pricing
Transparent per-message rates that drop automatically as you scale. Not plans, not subscriptions, just honest pricing.
Message type
Pay only for delivered messages. Failed sends are free.

FAQ
No provider is cheapest for every destination, volume, contract, and traffic pattern. Wevlix publishes its destination-based price, has no monthly minimum, and charges only for delivered messages so you can compare your real cost before migrating.
Use your current all-in SMS verification cost per successful delivery as the baseline. At 10,000 monthly verifications, a 70% reduction is possible when that baseline is at least about $0.0220 in the US or $0.0877 in the UK, based on the Wevlix rates shown on this page. Your actual savings depend on your current provider, contract, delivery rate, and volume.
WhatsApp can be the primary verification channel for users who have WhatsApp. Keep a fallback such as SMS, email, passkeys, or recovery codes for users who cannot receive WhatsApp messages.
Wevlix bills on confirmed delivery. Failed or undelivered messages do not deduct from your wallet, which makes cost per delivered verification easier to forecast.
No. Meta can update destination and message-category rates. Wevlix pricing also changes by monthly volume tier. The live calculator on this page is the current source of truth before you send.
