Nokia 6200 unlock problem

[derteejohn]

Hi,
I have a Nokia 6200 which is locked on UK Vodafone.

I tried using the Nokia Free Calculator on these settings:
Nokia
6200 (NPL-3)
IMEI: <removed>
United Kingdom
Vodafone
MCC+MNC 23415
Asic 2
V2

These are the codes which it came up with:
Model: Nokia (6200 )
IMEI: <removed>
Network: 23415000

<removed>

I've tried other calculators & they come up with the same results so the codes must be correct.

First I tried this twice & came up with code error
<removed>
Next I tried this code once but also code error
<removed>

I did notice that my Vodafone prepay card will work in this phone but when I put my Vodafone contract SIM in I get 'Invalid Sim' error.

Would this mean that one of the other locks are closed as it works one one Vodafone card & not the other.

Any ideas???

Thanks in advance.
