Default [Q] No sim card error problem note 2 tmobile

Hey guys! This is my first time on the boards and of course, I'm in need of some big help. As of now, as the title states, I currently lack sim card functionality. Unfortunately, I believe this is in many ways is my fault as I was deleting some bloatware off my phone... the three that I deleted was the stock internet explorer, a T-Mobile application (forgot the name) and an app called "talk" all of which came on the phone. Everything was fine up until I restarted the phone. My phone is rooted. My backup failed, so I'm in the process of downloading the stock ROM, will that help? any info is appreciated at this point. Anyone has any idea on how to go about this?
