I 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. I was also asked to delete other apps to dowmload it.! While I have a huge memory card that's free. I downloaded it on Samsung Note 5, it worked !!! They must change their software engineer I guess😕

Does not work. "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 FIX

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. and did not get any sms. everything is correct no mistakes double checked country and phone number. it's been 25 minutes after this third time try but sms yet. 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.
