I have a new Samsung Galaxy Ace GT-S5830D. I am with Koodo/Telus and when I have signal it shows up as koodo or Telus and phone works fine. I live in a little town in the country and barely any Koodo/Telus Coverage and my phone jumps to a rogers tower which gives it full signal but my cannot make calls or SMS, Shows full bars nut reads Unregistered Sim and reads mobile network not available when you try to place a call. Does Koodo just not work on rogers towers? and if so is there any way to get it to stop picking up these towers?
