Ok, my simm is unlocked BUT there is a security code!

[Mkguitar]

Nokia 6600 ( ebay) telefonica movistar ( spain) I've unlocked the simm, and the phone sees it, but it has a lock if the simm is changed.
The 5 digit code is not the 12345.

So what should i try?

Also how about a source or flashing to get rid of all the telefonica stuff and put T-mobile stuff on there?

I use Tmobile in the USA.

Thanks, mike

your gonna need something like prodigy-box to flash the fone and fully get rid of the movistar software, although some can be deleted using a file manager app depending on its location.
Prodigy would also read or reset the security code for you.
AFAIK theres not another option
the security code can be anything from 4 to 8 (or maybe even 10?) digits in length
Have you emailed the ebay seller to see if he can help?
good luck
