Foreigners staying in Korea for more than 90 days must make ARC at the immigration office. On the backside of your ARC, Your duration of Stay will be marked in a year unit.
If you register the ARC on the SIM card, you might get the SMS notification when the Duration of Stay expires coming.
It says, " Your Duration of Stay expires soon. If you extend your Duration of Stay at the immigration office, please re-register your DoS to customer service. If you didn't, your SIM card can be suspended. "
Like the notification, when you extend your Duration of Stay, you have to re-register your duration of Stay because 7 mobile does not know your personal plan! If not, your SIM plan will be suspended at the end of your Duration of Stay.
Registering is simple,
1. Take a picture of your ARC front and back (Duration of Stay) on the white background
Done.
When we got your attachment, we will submit your attachment at 7 mobile directly. When it's accepted, we will get you the complete email.
Please make sure that the photo must be clear to read and no light reflection!
