If so, I have a question. My girlfriend is telling me that there is some code she can enter into her phone before dialing a number which makes the call free but she does not remember what it is. Is there any truth to that? If so what's the code? I thought it sounded a bit far fetched.
Imagine your cell battery is very low, you are expecting an important call, and you don't have a charger. Nokia phones come with a reserve battery. To activate, press the keys *3370#. Your cell will restart with this reserve and the phone will show a 50% increase in battery. This reserve will get charged when you charge your cell next time.
