The basic functionality is be able to call and receive call, but now you are telling me that I can't receive calls from whatssap in Portal. I wanted this device for my grandmother so she will be able to receive videocalls easily from her loved people but if she can't answer the calls this is a waste of money, she will be using her cellphone as always because this basic phone functionality is a lie, the worse is that you show a complete functionality is your ads and that is not true!!!
