So I just got an iPhone 6, one of those used ones they sort of "fix" to make it like new, and I have had it for a few weeks, and it's bern fine. But ever since this morning, it will either say searching or no service. Plus I can't use my cellular data. It won't even show who my carrier is. I updated to iOS 11.1 and 11.1.1 and my phone started workout nvm properly for a few hours, but now it is back to searching or no service. I have hard restarted my phone, reset all settings, updated my phone, and removed and put the SIM card back in. Nothing is Working. Can someone help?
