How long do numbers stay active?

If you're not receiving messages, try these solutions:
- Wait 1-2 minutes - some services are slower than others
- Make sure you included the country code (e.g., +1 for USA)
- Try a different number from the same country
- Check if the number is still active (green status indicator)
- Some services may block virtual numbers - try another service
Can I use the same number multiple times?
Yes, as long as the number is still active. However, many services don't allow the same number to be used for multiple accounts. Each service has its own policies.
