WPA 10 digit phone number using area code dictionary and 7 digit mask? HOW?

[ICONOCLAST]

ok here is what i have:

./hc -m 2500 -a 6 hccap-combined3/combined3.hccap /media/hal/My_Passport/WORDS2/AREA_CODES/areacodes.txt ?d?d?d?d?d?d?d

where ./hc is a shortcut for hashcat.bin
and areacodes.txt is a simple list 387 lines long - just 3 digit area codes

it works but,
Here is the message:

hal@ubuntu:~/hashcat-3.10$ ./hc -m 2500 -a 6 hccap-combined3/combined3.hccap /media/hal/My_Passport/WORDS2/AREA_CODES/areacodes.txt ?d?d?d?d?d?d?d

ATTENTION!
The wordlist or mask you are using is too small.
Therefore, hashcat is unable to utilize the full parallelization power of your device(s).
The cracking speed will drop.

This same hccap file with ?d?d?d?d?d?d?d?d?d?d (10 dig) runs at 146kH/s

Note: with -w3 at the end:
./hc -m 2500 -a 6 hccap-combined3/combined3.hccap /media/hal/My_Passport/WORDS2/AREA_CODES/areacodes.txt ?d?d?d?d?d?d?d -w3

the hash rate goes from 977 to 1026 h/S

Any ideas?
