Any ideas on changing NIP2 in SE Z600?

Posted by misaelt
See, I'm with mexican provider Telcel, and after contacting the technical team for information on how to change NIP2 code (and therefore input cost and long distance limitations on the Z600), they told me this is only supported in some countries. Mexico excluded, of course. Is this true? Do you all T610's and Z600's users can access the options for costs?

As far as I heared this feature depends per operator. We (in our country) call it PIN2. I think most operators block this, cause you can track your total costs very easily and the operators don't like it as you can stop using your phone as your time limit is reached.

Thanks. And yes, it seems that telcel has blocked this feature. I think I'll just need to unblock the phone... or is it a network problem? I thinks it's a nice feature.
