I get wrong numbers all the time in other languages. I only speak English fluently. The languages I studied previously were mainly in writing so speaking other languages is quite intimidating for me.
Top languages in my area: Spanish (mainly Mexico and Puerto Rico), Vietnamese, Korean, and Russian. I’ve also encountered Igbo, Yoruba, Arabic, and Haitian Creole.
Learning how to say something like “I only speak English” would be helpful as well.
I did find this website but I have no way of knowing how accurate it is:
As a practical point, saying it in English will almost certainly communicate what you need to communicate. Almost everyone who makes international calls will recognize that you’re speaking English even if they don’t understand what you’re saying, which suggests that the Russian or Korean speaking person they’re trying to reach is not at that number.
