What app do I need to install when I go abroad to work? Do you have any recommendations?

Working abroad is a business trip. It's nothing more than making phone calls on the internet. I want to share my method.

Before, my friend asked me to try mobile worry-free, saying that there are still many tools to use, such as translation, overseas exchange rate, information, various strategies for booking hotels and scenic spots. Basically, it is enough to install an app, and there is no need to install anything else. Basically, everything you want is on this.

Most importantly, it can completely solve the traffic problem, and it is fast and affordable. There is also a free national voice call. Answering the phone and sending text messages are free, which usually takes a long time. You can also display your phone number by calling customers without worry, and you can also prevent strange overseas calls from being hung up.

It really helps people like us who often travel abroad on business.
