Hey guys. How is everybody?

I just wanted to know something. What happens if someday I cancel the service with my network provider - in this case T-Mobile USA, my phone really dies or not?. Once I tried, I took out the SIM card and the phones didn't do anything. Does this phone (SE K850i) only works with SIM cards?. Maybe later I just want the phone only to listen to music, without SIM card, there exist some trick to do this?

One thread says something about Opening phone without a SIM card: **04*0000*0000*0000#, after I press the # key it says Wrong PIN, only 2 attempt left. What should I do?



Thanks everybody for helping in this



Sorry for my bad English.

we called it unlocking.. try using third party applications like setool2lite,x++ etc. or try reflashing your phone.. but if theres something to do with the gdfs, that might be a problem.

Leave the sim in your phone . It works with an inactive sim.
