What's the difference between a second-number app and HeyNum?

Second-number apps give you an extra number inside a mobile app, often with an identity check and, for some, a web version reserved for premium plans. HeyNum gives you a real mobile number that works in any browser — computer, tablet or phone — with just an email address.

Is a second SIM or eSIM better?

A second SIM or eSIM gives you a full mobile line on one phone, including emergency calls, but it needs a compatible phone, a contract or ID in most countries, and only works on that device. HeyNum works on all your devices and is live in seconds — but it isn't a replacement for your main line.

Why not use a free calling app?

Free apps are funded by ads and data, their numbers are often rejected by apps and websites, and they can be reclaimed if you don't use them. HeyNum is a paid, private service with real mobile numbers that stay yours while your plan is active.
