"No Service" after battery change on iPhone 5
I replaced my iPhone 5's battery today following the iFixit instructions. Everything appeared to go smoothly and was trouble free. After the replacment, the device was powering on, charging correctly, all buttons are functioning as well, and Wifi connections work just fine.
However, I can't connect to the cellular network. I have updated the date/time via settings and rebooted the phone. I also reset network settings and finally reset the entire device back to factory settings. However, I keep getting the "Searching" message on the status bar followed by "No Service".
Any idea on what went wrong?
