I have an S7 and entering these codes doesn't do anything for any of them. am I supposed to do something after typing a code in?
Hello Fraenk
You just to type the code and then you will be automatically taken to a new window.
If you bought you mobile with a contract then these codes might not work as the service provider must have blocked access to these codes.
Try*#0011#

Hi, I have unlocked my S7. I can make text and calls but LTE is greyed out and cannot add/ set up a new APN. I cannot see 4G on status bar. no internet.. can you provide a fix pls?
I am trying to get into the service menu for band locking etc. *#0011# works and I get into the main screen. But none of the combinations work from that point when put in via “Key Input”. Generally you press “back” and then “Key Input” — “Q” followed by digits. Any ideas ??
Hello, my s7 i think is block by operator , how can i make these codes work , because none of this is working !
When you buy a mobile with contract then most of these codes will be blocked by the operator. You can always search on Google for your operator codes and the basic one will always work *#0*#
