How to use WIFI when traveling? How to use the Internet artifact?

There are several ways to use WIFI when traveling:

1. At present, all major shopping places and hotels in China basically cover WIFI signals.

2. You can buy or rent mobile WIFI to ensure Internet access at any time. This device can meet the needs of 3-5 mobile phones at the same time.

Don't use the so-called internet artifact. First, it has great power and radiation. Second, it belongs to illegal internet access, and the signal is extremely unstable.
