Hmm ... you can try this one instead: [STOCK][FTF]Z3 D6633 - 23.0.F.1.74 - dual-SIM variant.
Maybe this works better for you.
If not, please register on xda and ask in the Xperia Z3 Q&A, Help & Troubleshooting forum.
EDIT:
I just saw that you have already posted your question in the Q&A forum (http://forum.xda-developers.com/z3/help/network-signal-upgrade-to-23-0-1-f-0-96-t3017929).
So now be a little bit patient and wait for some to answer your question there.
Thanks for your understanding. Thread closed.

Probably because you didn't explain your issue properly.

factory reset
or, change your sim card and try to call your own number
or, change your firmware (try U firmware since your S7 is on ATT firmware).
