1. "Unfortunately, a problem has occurred and Numberbook cannot be opened You can identify phones numbers by using our WhatsApp bot until we solve this problem." When I click on the WhatsApp link I get this error: "You seem te be trying to send a WhatsApp message to a number that is not registered with WhatsApp...." Please FIXI deleted the app since it was all the time asking me to watch ads in order to give the numbers!!! I downloaded the Numberbook again (might be a newer version) right after And it's not working at all it freezes then I turn it off then delete it then download it many times still not working.

2. I downloaded it on Samsung Note 5, it worked !!! They must change their software engineer I guess😕It came out with the idea, now it became completely useless... I couldn't use the app because of the dark ages verification methodsJust watching ads without getting numbers please fix the error .

3. and if it comes it would be late because of the time limit that does not give you a rest to wait that activation sms might come through.I have been getting calls and messages from unknown numbers since the past 2 years now.

4. and I buy premium but still advertisement is viewI tried to verify my mobile number but each time I made the attempt, the timer countdown rounds down and I have not been able to use the app.

5. Before i was able to get numbers when i watch ads but now it is not workingBeat app to search phone numbers by name and vice versavery slow .

6. Any suggestion, please?for the third time with all their tries, I could not get clear activation call, I did answer the call that lasted for 3 seconds but there was no sounds.

7. it's been 25 minutes after this third time try but sms yet.

8. But unfortunately after the last update keep giving me error saying that the app can't connect to the internet although my internet connection is fine.

9. everything is correct no mistakes double checked country and phone number.

10. I was also asked to delete other apps to dowmload it.! While I have a huge memory card that's free.

11. It would have been better if the app shows the verification code in notification bar.
