First in the contract, the O&M account provided is a tools for the vendors to help the operator, still it is the operators property. Any Unix admin knows how to change those password, nothing special. The back doors opened to those account are pretty simple stuffs to debug the system. If needed however, the operator can simply disconnected the modem hooked to the MM or switch to stop engineering access. Because every countries have their own laws regarding cell phones, or in general phones. Every release to the operator from the vendor has to comply with those laws, therefore every countries get same release with different configurations. It takes an effort for the vendors to track the releases and configurations to different operators. The contracts between the operator and the vendor usually states that the adnomal dropped calls translate into panalties/financially to the vendor. Therefore, in the case you said after upgrade, the normal calls dropped due to misconfiguration shipped from the vendor, and that means the vendor had to pay the panalty. I know it because I'd been in the seat review this kind of field report, and the managers asked for review release process and ensure the people who were responsible for that knew about the problem. Also we were asked to give recommandations to ensure this kind of problem would not happen.

If you are intersted, see if you can track Donald Tsang's cell phone. The answer is simple, you can't, because you don't have enough information.
