So if the captain got a phone call from an unregistered phone do they have a recording of what was said? Or how do they know it was a woman?
Presumably if the phone was bought by a woman who gave false id it may not necessarily have been a woman buying it. It may not have been a woman using it.
How common is it in Malaysia to buy a phone and register false info? Is it something that may be checked, or is it like us giving false details to commercial companies to avoid endless marketing emails and phone calls?
Would people who were having an affair, for example, be able to easily buy a second phone without giving correct details, and would it be reasonably commonplace, or is this a very significant piece of information?
