I am about to embark upon an exciting new job, and I'm having a dilemma regarding my smartphone. My new job will not give me a phone - rather, they will reimburse me for my bill.

I would like to only carry one smartphone and so my question is as follows: Should I purchase a the smartphone I really want and use a single phone number for personal and professional calls? Is this as scary as it sounds or does it not make any difference in the real world? I kind of hate the idea of wondering if a call is about work or a personal issue. Any thoughts from anyone who has had to use one number for work and personal calls?

On the other hand, I could purchase an unlocked Lumia 640XL Dual SIM. The benefit of that would be that I could have two numbers (one work, one personal) pointing to a single phone. The down side is that it's not exactly the type of phone I want.

So what does everyone think? Is it better to have a Lumia that has two numbers dialing to it, or should I take the plunge and use a single number for every aspect of my life?

Thanks in advance!
