Welcome to BlackBerry Support Forums
You can always try an Software Update / Reload , it may help but will never do anything wrong with your device
But you should also call your Carrier Cell C and ask them if they have any issue with there network or try a SIM swap . If issue persists even after a Software Relaod and replacing SIM then it may a hardware issue .
