You should get a free month of premium credit with your camera. Use it so you can experience the web portal and the app. No text messaging involved. The app and web portal are my favorite features of these cameras.
The camera sends the last photo of the series it takes so most of us set the camera to 1 photo.
I set our cams to 1 photo, 5 MP, 0 seconds between pictures.
Set the time zone on the camera.
Once you're set up on premium, you can tinker with any settings using the app or the web portal (and browser).
Unless you need to control the camera real-time, you will save battery by leaving real time control off.
You will get a status report every day. If you are using the app, you will probably want to set the camera to send you photos at least a couple of times a day, unless it's in a high traffic area. We get photos at 9 AM and 9 PM (so a daylight and a dark no matter what time of year). That reassures us that the camera is still there and that it's working. For some of our cameras, that may be the only activity for a couple of weeks.
There's probably more, but this is what comes to mind right now
