The PoS cellphone I use when travelling abroad has the bad habit of accidentally triggering all sorts of functions when I forget to explicitly lock the keyboard (stupid brick-body designs). Instead of staying nicely asleep in my pocket, it will kill time by calling random contacts from my address book or navigate half a dozen menu down to some obscure settings…
Last week, upon glancing at my message logs by chance, I realised it decided to send half a dozen empty messages to the first contact in my address book. It then topped that series with an audio SMS: 30 seconds of muffled sounds from whatever crowded bar I must have been in, that night.
All that while using a throwaway number on a prepaid German SIM card (thus unknown from most of the people in my address book).
Meanwhile in Europe, my friend Abigail is probably ever so slightly worried by that mysterious German caller who sent her all these creepy empty messages.
