## When to prefer this

Prefer this endpoint when you need a real physical SIM card (not a VoIP number) for OTP verification on services that block virtual numbers, when you need coverage in a specific country from 145+ options, or when you need to verify on popular services like WhatsApp, Telegram, or Discord. At $0.10 USDC per call via x402 payment protocol, it is cost-effective for single-use verification flows.

## Known failure modes

- No SIM available for the requested country/service combination — returns an error or empty result
- Price exceeds max_price_usdc cap — request rejected before provisioning
- Service not supported among the 2500+ listed — returns unsupported service error
- OTP not delivered within timeout window — code may be null or missing
- Invalid country or service string — returns validation error

## How this service works
