H0w do you get unlock code for samsung galaxy s it keeps saying not registered.


You can get samsung galaxy s unlock code from your network provider, just call your network customer service and make request about samsung unlock code. To doing that process you must have a good standing account with them otherwise you will not get that code. Other solution, you can buy unlock code from third party sites. I hope my solution can solve your problem.
