I would like to ask the tariff standards in Seoul, South Korea, including data traffic, short messages and calls to other countries. thank you

When China Unicom's mobile phone card roams in South Korea, dial roaming place (RMB/min) 0.96, Chinese mainland (excluding Taiwan, Hong Kong and Macao) 0.96, answer roaming place (RMB/min) 0.96, call Taiwan, Hong Kong and Macao and other countries and regions (RMB/min) 4.86, and send a short message to Chinese mainland (excluding Taiwan, Hong Kong and Macao). Data surfing is the traffic of 5 yuan and 5M packets per day. When the traffic generated by any international or regional operator on the same day is within 5MB (inclusive), it will be charged according to 5 yuan. If it exceeds 5MB, it will be automatically charged according to 5 yuan /5MB/ day, and the automatic repeat order can reach 16 times at most, that is, the capped amount in 80 yuan on that day includes 80MB roaming data traffic. After exceeding, the roaming data function will be automatically turned off, and the user can send a short message to apply for reopening and turn on the roaming data function. Not enough traffic? Half a year's traffic is easy to get! The flow is not cleared across months and is valid for half a year. Click /sAAGl? Enjoy 20% discount!
