I would advice against it, unless you don't mind answering (or ignoring) thousands of tax advice texts that you get form your clients through this phone. Then they will start texting you their 1099Rs, "Oh, just got this, please add it to me tax return", etc. Even worse, they will text things like, "please add a $640 insurance expense to my P&L, I just found the bill I paid."
My Doctor, for example, will send me texts for needed things, but he sure wont answer one of my texts. So that's one possible route.
I don't answer tax texts at all nor do I give out my cell number. That's why I have an office phone, email, and pay employees to answer and process them.
We are high volume and bypassing those contact points throw a wrench in our systems.
