Re: Common NAM Performance Tweaks.
ACCOLC was explained to me like this:
0-9 everyday use for all normal people and that most carriers use the last digit of your phone number to select this. Also higher numbers are better. (eg phone numbers ending with 9 work better the ones that end with 0)
10-15 EMS and GOV only - use these without permission and you could be charged or fined.
