Comments on NumberBook- Spam Blocker for Android

★★★★★ elias sader · Oct 27, 2025

I changed my phone. I deleted the Number Book application in the old one. Now, in my new phone, trying to subscribe by WhatsApp(as required), no activation is done. I received several times: "invalid number". I have now the application without activation.

★★★★★ Mohammad Dweik · May 14, 2026

The app is very helpful and nice. But at the right time it is not working. I contact the support via WhatsApp but no one replied. I hope you fix the problem

★★★★★ inside edition short · Sep 14, 2025

Please fix problem verification I tired verification 😔

★★★★★ sogand nazari niya · Jul 20, 2025

It was a good news program. But for a long time, whenever I enter a number, it doesn't show the name of the contact. Whenever I give it a number, I get this message (No Search result yet, Start discovering the World!) Please guide me as soon as possible, thank you.🙏🏻

★☆☆☆☆ Amir Hesam Noroozi · Nov 28, 2025

After switching to a newer phone, I encountered this verification problem. WhatsApp, Telegram, and call/SMS options are all not working. Call/SMS error says my number is an invalid one. The exact number I used in my older phone when signing in to this app.
