If you want assistance from the Community Forum then you need to explain your issue or question clearly.
What exactly are you trying to do, what steps are you taking to do it, what happens/goes wrong, any error messages, etc.?
What exactly do you mean by "SIM locked"?
What exactly are the symptoms of the problem?
When was the SIM working ok last?
What changed in the meantime?
E.g. phone software update, settings changes, factory reset/restore, new handset, returned from roaming abroad, etc.?
If you need to contact 48 support about this then see the links in my signature below.
