Hey guys, So part of my job I have to be sorta "on call" 24/7. I work for a big company and manage an application, so if I goes down anytime I have to be able to respond very quickly. Right now I have it set so it sends an email to my cell# (which is basically a text) that alerts me of any downtime. But the problem is sometimes I sleep through these if they come at 2 or 3 am. Especially if my phone is on vibrate. So what I'm wondering, is there a way to set a certain text to like keep alerting me, or ring only for that text? Or maybe an app that can help this? I don't want to carry around a pager if I don't have to.
