How to check the phone bill balance of Korean mobile phones?

Korean mobile phones are almost unbalanced.

Because South Korea is almost always an installment machine. Generally, LG, SK and KT are the three major communication companies.

The monthly phone bill is automatically deducted from the bank card according to the package fee and the installment fee.

You know when the contract expires.

Only a small part is prepaid, which is what China uses now.

Moreover, this kind of card is operated by different small communication organizations, and each company has a customer service phone number, so you can ask when you call.

Or text messages to remind you when you are about to owe money.
