Forward texts from one iPhone to another?

Here's my problem. I've had an iPhone I use for my personal life, but recently my company required we use their iphone that are pre-setup how they want them. So now I'm carrying two phones. I have everything from my personal iphone forwarded and synced to my business phone except texts.

For example, if someone texts my personal phone, i want it to be automatically sent to my business phone. I know I can change things on my plan, or just ditch a phone, but that wont work for me for other reasons.

Is there a setting or an app or anything I can do to have texts forwarded between phones? I know in Settings > Messages, there's something that says "receive at: 'my phone number'". It's gray though..
