1. Can one person book multiple SIM cards for friends and family?

Yes, 1 person can book up to 10 SIM cards, however, please note the SIM card usage time starts counting from the moment you pick up the SIM card from the airport.
If you would like to pick-up your SIM card then activate it at a later time, please choose the Hong-ik University Office pick-up location. Please keep in mind that you will need to install the SIM card by yourself with this option.

2. I am using Samsung S6. Is it the right sim card for S6?

Yes, the SIM Card help desk will issue you a SIM card that fits your phone model type(nano, micro etc). They have different SIM cards for each different phone type. Price is same for all sizes. 

3. Can I extend the date?

Sorry, Date extension is not available.

4. Can I use the sim card with my wifi router?

The unlimited data SIM card can be used with your own portable wifi router. However, additional processing is required in order for the SIM card to work properly with wifi routers like changing the APN settings. These settings and functionality of each wifi router vary per device so the telecom staff cannot assist you with updating these settings. If you are able to setup the wifi router yourself after retrieval of the SIM card, then the SIM card can be used. If you are unsure how to process these changes, we do not recommend you purchase this SIM card for use with a wifi router.
