It shouldn't have been possible for someone to obtain the contact details of a military-issued comm. By default, they blocked all incoming contacts from unknown sources. This prevented the comm from being influenced by malicious code and annoying ads.
Not even most of the Vandals possessed the privileges to send a message to his comm. The only ones who possessed the necessary qualifications would either have to be a chief technician, a mech designer or a senior officer. As for the rank-and-file, Ves wasn't interested in hearing them out.
For Calabast to obtain his contact details, she either retained the services of an extremely skilled hacker, or she accessed the comm of one of those people mentioned above.
Ves grimaced even further. Calabast not only had the ability to contact him willy-nilly, she also knew about their escape plan. "The thing is, even if there's an issue with the Big Breakout, why are you approaching me of all people?"
