well it sound strange jaja but it works for me.. i did this: i deleted my account from the account manager then open wazapp, and in the country code my country code and the first digit of my 10 digit number.. (in my case i live in mexico was +52#, the # is the first digit of my number) and then where you put your 10 digit number i just put the 9 digits left.. 123456789.., i get the sms and thats all i was able to login dunno if this works in other countries.. but at least in mexico it works xD
