Hello after changing the glass of my iphone comes out I try to no sevizio, sometimes it works for 2 hours. the antenna cable is damaged will be what the problem or the baseband? and not have menu carrier but the phone have imei !!
Did you try to make a network reset? Simply in settings>general>reset>network settings. It will reboot and then you can go back into settings>general>about and check if you still have IMEI and Baseband. Sometimes the modem firmware and IMEI doesn’t update until you actually do a reset and it has to re-read it. However, if the antenna is broken then it’s most likely the problem.
