real phone number

Do you always provide your real phone number when registering online anywhere?

If a service truly needs my real phone number (for banking, healthcare, or critical security purposes), I provide it. But for forums, trials, downloads, or casual services, sharing my personal number often feels unnecessary. And I use Gettempnumber tools which will provide temporary numbers. In my opinion, using Gettempnumber tools as a verification method is a reliable and practical option in many cases.
