I have recently moved to Canada from Ireland and have brought my phone over with me – it's a Samsung SIII Mini GT-i8190 model. I checked with Koodo online and their site says that this model should support a Koodo Prepaid SIM. Staff at the Koodo stall where I bought the SIM had no demo's available so I just purchased the SIM and have set it up, placed it in my phone but it will not recognise or connect to any network. So no calls nor texts. The phone is unlocked, there is no prompt for an unlock code and I'm not sure where to go from here. Anyone any suggestions?? Thanks!!
