Have you checked to make sure that the firmware of your phone is stock? Have you only rooted it or added customs roms as these can in some instances after the coding within your phone not allowing an cellular contact. It's a pretty complicated thing rooting.
The best way full proof to unroot your device is if you flash your firmware again. In that way you loose the root and all traces from it.
Turning your device standard again.
