What will you do...
...If you lose your phone?
Definitely, I will cry pretty much If I lose my Samsung Note 4. :(.
Don´t think about it.
If I lose my phone
I will use an old phone that I have in a small drawer on my office.
To live without phone
I think too, I will run out of smartphone for a year. I will live again. :D
To save money
If I lose my phone I will save enough money, so I will see if I will use it to buy another phone.
