Android remote texting app

[RossMAN]

I have an LG G Pad X 8.0 tablet (5.x Lollipop) and Nexus 6 (6.x Marshmallow), both with active SIM cards, tablet is text/data only. Both are logged in to Google using same gmail address.

I'm looking for the perfect free or paid app that offers:
1) Automatic forwarding of ALL incoming text messages including MMS (pictures/video) from tablet to cell phone. Probably an average of around 100 texts a month.
2) Remote texting from cell phone using my tablet's phone number.

While I'm on the topic of Android apps, I have a personal and business cell phone. Can anyone recommend an app that will let my personal cell view my business cell's call log remotely? Probably an average of around 12 incoming/outgoing/missed calls daily.

Sms backup+ has the side effect of making your SMSs and call logs available in your Gmail so you could use that to view things across devices.

Thanks for the suggestion it looks promising.

I should have mentioned the tablet plan doesn't offer a lot of data. So I'm searching for more of a text MMS forwarding app?
