Bold 9900 randomly shuts off mobile network and turns on bluetooth etc

Greetings,
 This is my 2nd Bold 9900 which does this. Sometimes 3 times a day and sometimes I'll get through a week without it happening but the mobile network shuts itself off. Then with other times the near field communication and or bluetooth will turn on. This is a work phone. On the weekend I did an update to the BB ID and it rebooted to a JVM 505 error so I had to reload the OS and I'm up to the latest of 7.1.0 Bundle 2840 and it still does it. I've talked to other people in other departments and some of them have the same problem. But then again not all 9900's do it. This is my 2nd 9900 and both had the problem.
Anyone else had this problem?
Thank you,

Hi Kennyboy5,

If you have already reloaded the software and the fault persists, I would check the warranty on the handset and get it replaced. Although this all sounds like software problems, there may be an underlying physical fault that you will not be able to fix.

Hope this helps,

Mike

Thanks Mike.
 Don't you find it strange that it's my 2nd one with the same problem? It's like they keep shipping out faulty hardware?

Thanks,

Hi Kennyboy5,

It does seem very strange. My first thought went along the lines of: "Someone must be pranking you." but I have no doubt that you would have spotted that. The fault sounds like a software issue. What you might want to do is download a local copy of the latest-but-one version of the handheld software and install that. Take it back one version and see if that resolves it. This is extra hassle for you, though, so a warranty replacement is probably the easier route.

Regards,

Mike
