Hi there and welcome
The only other solution you have Joy is to use an unlocking service to bypass the lock on the phone.
It's only done by a limited amount of companies with the best one being this
As they are licenced to do this
They do change for the service, but if you wish to bypass the lock its the only method to get it unlocked.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
