Thanks for your response. I know that i can import contacts or use my google account, but i dont know why i cannot do the thing that was ok on galaxy mini and not on X8.
Most of the roms of x8 are based on CM, that doesn't use sim contact. So i have tested most roms but allways the problem. I think it's just a parameter problem or soft problem, but where to do it ????
And for zmuhammx, yes i was registered on most forums, with not a lots of activity, because i spare a lot of time to read, re-read and search on post to find the solution of my problem without post a lot. First i read, second i think and if really i was blocked i post.
Second thing, since 2008 i'm renovating an old house and i just have finished. So no much time to spend (very tired).
So now i have some time to work on android, so i became to put my nose in roms and if i find the solution i post it.
At final, in france we pay a lot for nothing. it's just now that we can have cheaper, unlimited acces to internet over gsm network. But network was very old. So from april 27 i can synchronise my contact with google (the best solution).
Thank to the XDA community.
