invalid card on XT1060

hey so i have an xt1060 bootloader unlocked which i updated to 5.1 and it stoped reading my sim card and shows invalid card. so i returned to 4.4.4 but i still have the same problem i even tired flashing the radio/modem but still no success. help??
also from the phones info i see <bootloader>sku: xt1049 dunno if it has something to do with any thing

It could be a bad SIM card, it could be a defective SIM card port, it could be a bad radio - it's not something we can troubleshoot online. It has to go to a repair shop. (I'm guessing it's a hardware problem and probably won't pay to repair.)
