What happens if the network signal on your BlackBerry SmartPhone that we have arrived - got error or lost and that appears only signal "SOS". SOS signals usually arise when we are in the area that there is no signal at all. But at that time we were in the home, workplace, campus or region - the area we used to be there. And the most annoying if it happens while we are busy with a bunch of call or BBM's or surfing.
This can happen because there is no signal or interference operator or there is a problem with the SIM card that we used as SIM Card has been worn away by frequent open - tide so ill-fitting or loose.
To overcome this there are a few steps you can try:
* Make sure there are no problems with the network, check whether there are signals friend's phone. If there is no problem with the network, turn off your BlackBerry and you try to check the installation of card or SIM Card (you should uninstall and reinstall).
* Replace your BlackBerry SmartPhone battere and recheck whether the signal is already there. If it turns out there is no signal to do the next step.
* Check with the incoming signal on Manage connection -> Mobile Network Options. Try to set the options to manual Network Mode Selections. If it turns out this way still does not get the network, do the next step.
* Perform Re-registration on HRT (Host Routing Table). Enter the menu Options -> Advanced Options -> Host Routing Table. Press the Menu button select Register Now.
