Default Galaxy s3 t999 wont read sim card after unlocking

I need help with my s3 from tmobile, i unlocked it using one of the guides on this forum, had to go from 4.2.1 to 4.1.1,(*#197328640#) then when i went back to 4.2.1 it would not register network(still using tmobile sim card) went to update and got the 4.3 and now it says insert sim card when i go to mobile network, I already check imei number and its the same as in the sticker on the back of the phone, the sim card works on my other phone so I would appreciate any help

Perhaps dirty Contacts. Wipe the contact with a spirit wipe. While wet, insert into the slot and eject immediately and wipe second time.

If that doesn't work you might want to try a different known working SIM. be mindful of static discharges carpet for example.
