Everyone should have a second phone
Having a device that is always on is a huge advantage. Especially when it comes to personal life and work. It is way easier to switch between work space and personal space this way, without moving between multiple computers and windows.
These days there are so many apps that we have to juggle through. The best way is to separate them into 2 phones, one for personal use and one for work. Even if you have only 1 phone number it’s better to have 2 phones. Just for the convenience and the multitasking. Get a cheap one for the secondary use.
Even if you don’t get many calls or messages it's well worth it.
