Free calls on nokia mobiles!!

This technique works on most of the nokia models out today. Meaning
this will work for you as long as you don't have an old fossil sort
of model. So what you will first do is turn on your phone. Then punch
in the code *3001#12345#. This will bring up the NAM programming menu.
From here go down and select the option NAM 1. Once you are in the NAM
1 menu, go down until you see "Emergency Numbers", and enter. You then
go down until you see an empty slot and enter the empty slot. Then
simply punch in the number that you want to call and exit the NAM
programming menu. Now when you dial up the number, the number will be
treated as an emergency call number, which will therefore put the
phone into emergency call mode (which you can exit out of once you are
finished with your call). No number in the emergency call number list
is ever billed to you. There are a couple of other things you can do
from within the NAM programming menu, but that can be saved for another
time, and another tutorial.
