    I have a T Mobile Mytouch phone and just this week I've been getting this new message of "Syn not allowed" I have no idea why it is doing it. I haven't downloaded a new app in over 5 months and even more so, it never tells me why, how or what app that is causing it.

    Even worse like the title says, it completely disables my phone signal to the point where I can't even make emergency calls. When I restart my phone everything works fine but then after a minute or so the message pops up and I can no longer call anyone and it ONLY happens when I get that message.

    I've tried wiping my SD card, unmounting my other SD card and for some reason this message still comes up and still continues to disable my calls. It's really starting to worry me since like I said, even the emergency call button can't over ride it either.

    Welcome to Android Central! If it's affecting your voice signal, then you need to speak to T-Mobile about it. Perhaps you need a new SIM card.
