Modified firmware that triggers on a receipt of a particular message and/or from a particular number?

Presumably some software that triggers this?

I see some reports claiming that the trigger message was “07734 58008” but hard to tell if all these accounts are serious.

My guess would be that not only the battery but also the main board was modified to initiate the action.

edit: why do you think I'm not sure if they are serious? Calculator jokes are not a niche humor :)

Clearly someone's not being serious.

Good catch. Your 3rd grade, calculator-using self is serving you well.

It's extremely hard to tell if these accounts are, in fact, serious

07734 58008 means "Boobs, hello". That does not seems serious.

The accounts may be serious (even accurate!) but whoever chose the numbers was not being serious in their choice of number. Or it's quite the coincidence.
