    Tegangan 0.1V atau 0.3V yg diukur, Gw yakin diukur tanpa simcard ataupun diukur dlm kondisi belum boot loading di atas 80%
    Karena dari pengalaman, proses pendeteksian n registrasi simcard pd waktu boot 80-85% utk bb normal tanpa aplikasi tambahan yg terinstall n tegangan normal bb tdk jauh beda dg ponsel merk lain, 1,8V/3V
    Coba diukur kembali dg simcard terpasang.!!!
    Umumnya kerusakan simcard yg sering didapati adalah short'e salah satu capasitor di jalur vsim/v_usim, terutama cap dg ukuran daya muatan yg besar
    Short disini tidak harus full short jika diukur dg tester, tingkat kebocoran 20% dr nilai muatan cap aja sdh bisa menyebabkan arus dr tegangan vsim drop
    Coba di ukur 1/1 Cap tsb :).. tidak banyak koq, hanya bbrp biji.!!!
