Hello, I am from Ukraine and I don't speak Spanish, so maybe I can get some help in English. I bought a ZTE Open in a spanish Movistar store, incl. prepaid SIM card. Now, back from vacation in Spain, I would like to use the mobile phone with my SIM. Therefore, I need to have a NCK Code (although it is a Telefonica SIM). I can't find any information about how to get the NCK code (due to lack of speaking Spanish). Where can I get this NCK code from? Thanks!
