How you do stay in touch with family and friends in different locations?

Hi! My name is Semyon. I'm interested in the matter of building relationships and staying in touch with people all over the globe.

Would like to ask digital nomads and expats here.
How do you maintain connections with family, friends and acquaintances who live in other places?
Like, does it come to you naturally, or you've developed some routine to maintain connections?

My habit is a call once per week, for the close ones, or regular texts (every few weeks or months) on messengers or social media, for friends and acquaintances. To set reminders and keep relationship history I use (and build) a standalone service.
