How can I use my mobile phone normally when I go to Thailand?

Steps to use mobile phones normally when traveling to Thailand:

1. Take the mobile phone number of China Unicom as an example, open the mobile phone business hall APP of China Unicom, click the menu item "Service-Handling" on the page, and click the "Switch Roaming Service" button;

2. Next, in the opened page, click the button switch to start the international roaming service, so that the mobile phone can still use the call service normally when it is abroad;

3. Take MIUI system as an example to handle traffic services. Open the "Global Internet Access" icon on the MIUI desktop, and click to enter the Global Internet Access Settings page.

4. Next, in the opened page, click and select the "Asia" menu item, and select "Thailand" in the list;

5. Finally, click the "Book Now" button. When the business is successful, you can use the APP to surf the Internet when you arrive in Thailand, and you can also get a relatively cost-effective traffic fee.
