Looking at buying the new note 4 but can it mirror my whats app?

I am after finding a way to copy my phones functions onto a tablet than will basically allow me too use all the wifi features of my phone with out having my phone with me.

I work offshore and have to leave my mobile phone in a bag at the heliport for 4 weeks and this is like loosing my main communication device.

I use mostly whats app for keeping in contact with everyone on the main land and this seems to be the stumbling point in this question.

Idealy if I could get a tablet to run my whats app account without my phone this would be great.

Moved from the Note 4 Accessories forum to the main Note 4 forum, since you'll get broader exposure here.

why cant you take the phone and use it on wifi? just confused
