I have a Viber account in my phone. I have installed Viber in my iPad using the same number. However, my phone has been stolen. Now I have another gadget and I want to install Viber there using my one and only account. However, putting the mobile number, it says "An activation code has been sent to your mobile phone, enter the code below:" and since I lost my mobile phone with the number registered in Viber, I cannot get the code. What can I do to install my Viber successfully in my new gadget using my original number?
