Hi all, I'm new here, so sorry for some mistakes from me and sorry for my bad English.

I have problem with mobile data. I have One S Snapdragon S4 version. I flashed Paranoid Droid ROM Jelly Bean, after some time, I have problem with mobile data, they are too slow, max 30kbps for download. So I flashed back to Venom Viper ROM to ICS, but the problem is the same. Before it, the mobile data was OK, but now, I can't load facebook, or download any app from Play and don't know how to repair it. Before this i have download abotu 10Mbps on 3G. Any idea what to do?

Thank you!
