I bought the Samsung GALAXY s2 from South Korea. What should I do to send text messages to people in China?

If you buy a Korean mobile phone from Korea, although Android supports Chinese by default, texting will be garbled.

You can try the following methods:

1. Brush machine. Use the optimized Chinese version of the system. Samsung can use odin software to brush the machine, or use one-click software to brush the machine (simpler, recommend "brush wizard").

2. Enter the SMS and press the function key to select Settings-Input Mode-Automatic.

3. Brush baseband files to solve communication problems. You can put the baseband file into the SD card and swipe your card. There are detailed tutorials online.

According to my three methods, I suggest you try step by step in the order of 2-3- 1 until you succeed.

I hope your mobile phone can work normally.
