Not sure where to put this, but if in the wrong place please move it. I havea casio that is my main phone. The samsung doesn't get any reception here. The only carrier that this phone can be used with in the us is AT&T. Which won't cover my area. I have an old version of the casio, and would like to tether that to the Samsung. Tried playing with the settings, and searching the web. The Glixy does not recognise the hotspot on the casio. Can someone please help?
