This is the first time I visiting Korea , my friends recommend me to get a sim from chingumobile. So I went Konkuk branch yesterday and get my card successfully. I have a phone which is redmi , I saw the price for android phone is 30000won a month , but the staff was very kind , she tested my phone very detail and she said I can get the sim by iPhone ‘s price , so I get my sim with a cheaper price at last ! It’s really helpful ! I would recommend my friends to chingumobile when they travel !
