Hi all, fist post here. I was looking for a physical pager, however they are pretty much non-existant. I was wondering if any of you knew of an app that can function as one? I tried the google play store. I found some apps, but they only worked for text. What I'm looking for is an app that can notify me maybe every minute for an hour if certian numbers call (not all numbers). When I'm in a truck or a tractor I rarely hear my phone. During planting and harvest it is important that I can call back if need be. Even if I do hear a tone, with ebay, facebook, email, text, and phone calls, I look at my phone and a lot of times it turns out not being important. Thanks in advance!
