That's an interesting point @hangggggbeeee. When I backpacked around the world there was no technology at all. No smart phones and not internet.
We always seemed to manage without translation though. Hand gesticulations and maybe drawing or pointing at paper maps. I don't remember it was ever an issue.
We also relied on books such as the Lonely Plant and Rough Guides but most of all we share information with other backpackers and learned that way.
Wishing you a fun week wherever you are! 😊
