No proof of its worth yet. Finally a chance to drive out of town. In areas where I had a reception bar or two with the signal on, I turned it off. Still had the same bars. Switched on and waited a while. The same number of bars. Launch the Speed Test app to test your internet speed. It doesn't matter that the overall result changes when the Surecall Max parameter is turned on or off. Repeat these steps in several places. Same results :(
