How should a person solve the problem of language barrier when traveling abroad?

My English is not very good, so it will not be difficult to communicate in many places. Just express the general meaning in a few short sentences, and the other party will understand. Worry-free travel by mobile phone download can solve the problems of internet access, language and route. If not, you can translate it into English or voice translation on your mobile phone. There is basically no problem. A carefree trip abroad is enough. If you take a taxi, you should translate the place you want to go to for the driver to see before getting on the bus, or you can communicate with the hotel front desk first, and then ask them to call a taxi for you and communicate where to go. Translation software and simple body language are for sure.
