I am using Nokia 5130. I used to download some good applications but of recent each time i try to download it will alert "no certificate in sim or phone". Pls someone should help me. What should i do to fix this problem
id try doing a factory reset ,all the certificates should be in the phones firmware you can add new ones and delete others but resetting phone should restore the default ones..ages ago i used to get certificate not trusted popups when enter googlemail ,,after googling it i found somewhere that had the new certificate ,i installed that and the annoying certificate not trusted dissapeared ,,,,goodluck google is your friend
