Do you have to know "English" to go abroad? Is it difficult to go abroad without English?

If you just travel abroad, have the Internet and a mobile phone, and arrange your accommodation and itinerary in advance, you can do it without English (I have many practical experiences of traveling abroad independently, and my English is particularly poor). If you are studying abroad and living for a long time, then English is a must. After all, if the time is long, language is the foundation in visa and life communication.
