@cabutcher99 so possibilities: First---- Did you root and flash a 3rd party ROM? IMEI corruption is known to happen a lot with these Galaxy S6. If you did, flash back to stock ROM and it will resolve it. Second---- EFS partition corruption Try to flash the stock rom again. If this doesn't resolve it, then you have hardware failure. Third---- Run your real IMEI (sticker on the back of the phone) through swappa.com or imei.info to check the number. If your phone was accidentally blacklisted, than you really do need someone to re-program to a different IMEI. Obviously, make sure you backup your phone's data before doing anything. Use Samsung SmartSwitch to backup all your texts, etc. You can re-download all apps via Google Play Store later.
