my unlocked rugby lte has been working fine with my koodo sim card for a few weeks. Then it spontaneously stated emergency calls only. When i attempt to call it states the phone is not registered on the sim. It shows full bars at home which is normal and the sim works in other phones. My parents bell sim card works in the phone so i thought maybe it was a temp unlock code so i brought it to the mall to get it re unlocked and they cant figure it out. They say it might not but compatible under koodo but they have no idea they have never come across this problem. Will it never work with koodo again? and why? i ask again WHY?
