HELP Can't find default text message app

[LookSir,Droids]

A customer of mine has gS3 and accidentally downloaded a texting app which replaced the default texting app

I have since uninstalled the downloaded app, hoping the default would come back. After uninstalling, I can't find the default app anywhere and I can't seem to even access a form of texting. I click on a contact, and the little envelope that normally shows up to press and send a message, is nowhere to be found. Please help!


thanks

just solved the issue. apparently when an app is 'disabled' it ends up at the bottom of the HUGE list under application manager -> all apps

when you 'enable' the app, it re-joins it's place in the ranks alphabetically
