Help stagefright virus

[stagefright virus]

Hello,
My oneplus one mobile has been attacked by stagefright virus. It came through MMS. I deleted an app for messaging through titanium backup. I rebooted my phone and still it is showing simcard is not detected.
Please help me with this issue.
Thank you

Stagefright isn't a virus, it's an exploit.

What happened exactly? Did you receive an MMS from a contact you didn't recognise? Did it contain a video file?

I presume you're rooted if you're using Titanium Backup? The safest way of removing it would be to install another ROM, is that an option?
