Activate Enhanced Full Rate Codec (EFR
 

Hi
I am sorry that I am asking stupid questons, but...

... What does the above mean please. If I activate the enhanced full rate codec, what does it do to my husbands nokia 1616? I don't suppose that it unlocks it at all does it?

What if I can take it back to Factory settings, does that unlock it?

Sorry if I am in the wrong section.

Thanks in andvance if anyone can help me

Caroline

You cant unlock your 1616 with efr or reset.
And EFR is sound quality.
