Thanks for your reply to my previous message. I will re-charge the existing sim card this month, will the expiray date extend? And will extend for how long?If I want to open a new sim card next year, how to cancel the existing one?  Thanks. Previous message and answer are as follow for your reference: Q: Thanks for your reply. My name in passport is WONG YEE FAI. So, if i want to use a nano sim card, i have to cancel the existing one???   Thank for your reply. My name in passport is WONG YEE FAI. So, if i want to use a nano sim card, i have to cancel the existing one?    I have purchased 2 sim cards last year. And i checked that one sim card is still valid (phone no.: 01027844396). I would like to confirm that I can still use this sim card, right? This sim car will expire on 2016-12-09. If I re-charge this sim card, will the expiray date extend?  Also, I would like to know that why another sim card will expire? If i want to purchase a nano sim and would like to keep it for using a longer period, how can i do it?   Thank you.    Ans: Hi, another number has already been terminated. If you want to use a new nono sim card, you have to cancel the number 01027844396.
Hi,actually your sim card should have been terminated on November 2015 cause you did not top up the card since September.
I think it's the system error so that you can still check the number.And since you didn't use the card for a long time, the card maybe has been broken. Thus, if the device recognize the sim card after arriving in Korea, you can use the card again. Or you need to buy a new one.
