I recently moved my data only mobile plan from 3 to Optus due to their support of fallback to GPRS at no additional charge (ie better coverage). Getting it to work on Mac was a trial.
Advisory: This is where I wax lyrical about pretty much anything I find of interest. Sometimes industry observations, othertimes anecdotes about my family. In essence this is the spot where I jot down notes on things that I find informative, noteworthy or amusing. If you do as well, I’m humbled & grateful for you stopping by.
