LG2 cannot connect to mobile network in China

[AC Question]

I bought a brand new LG G2 in the Philippines and used a local sim card and everything is fine... When I went to China today, I tried my local Chinese sim but it is not being detected... I am a noob on rooting or flashing by the way... thanks

You need to take the device to your carrier to flash it.
