Can I send short messages if China Unicom opens international roaming? Seek a major or try the Great Immortal Solution ~

As long as the international roaming is confirmed, it is ok to call and send text messages, but the tariff is definitely charged according to your international roaming fee in Korea. Text messages are usually about one yuan. Please consult Unicom customer service 100 10 for specific fees. I also want to remind you not to surf the Internet abroad. If you don't have to surf the internet, you'd better ask the customer service to turn off your internet access function, because the cost of surfing the internet abroad is quite expensive. There is a Unicom user who originally sent three Weibo abroad, which cost 3000 yuan, so pay attention.
