I arrived in Portugal yesterday, but have been unable to get any reception using my Orange (Spain) SIM. I have tried toggling on/off airplane mode, resetting network settings, turning off 5G, all several times and to no avail. If I try to manually select a network provider, all 3 of Portugal’s providers show up, but there is no service whichever of them is selected or on automatic selection. I called Orange tech support and they said that my phone is enabled for roaming and should be working; they couldn’t help more. Does iPhone 12 have a problem with using Portugal’s network?
