Looking for a dual sim phone

I've recently got a job requiring me to have a business phone. I'm looking for the best dual sim phone on the market, well as long as it's under £500 (under $800 if converted right?).

Currently have iphone but as much as I like the phone I'm getting tired of the restrictions. Something like the S5 or alternative?
