# Compare SMS verification services

The temporary number market has a dozen marketplaces that look alike on the surface. These pages explain how each one works and where SMS Nitro differs, without the usual chest-thumping.

## What is the best alternative to SMS-Activate?

Any marketplace that offers private numbers, charges only on delivered SMS and keeps an SMS-Activate-compatible API so your tools keep working. SMS Nitro does all three, with live success rates per country and a balance that never expires. The pages below cover each competitor individually.

## FAQ

**Why compare at all?** Because prices and success rates differ per app and per country, and the right provider for WhatsApp in Indonesia may not be the right one for Google in the US.

**Can I use several providers?** Yes, and many professionals do. The API is compatible with the most common protocol, so switching is a configuration change.
