How do you "disappear" for 3 months when people can contact you through phones?

There is a saying on Instagram: Disappear for 3 months, focus on goals and you will be unrecognizable!


How do I actually do it without blocking some people I don't wanna hang out with?

I don't wanna spend time with them because they waste my time and try to USE me,
but also I can't block them as they're colleagues, so how do I avoid their calls/texts?
