George asked us,
For some reason my BlackBerry is now showing ‘SOS’ where the reception bar indicators use to show. No emails are received and I can’t place any calls.
The SOS indicates that you can only place emergency calls. Usually this means that you have a bad SIM card in your device, either one that has been corrupted or one from another carrier that is not compatible with your BlackBerry. You will either need to replace the SIM with a SIM from the carrier of your handheld or get your BlackBerry unlock. This feature is actually something that the carriers don’t really advertise. Where you are able to place emergency calls to 911, even if you don’t have a carrier account, just need a working cell phone.
