How is an international SIM card different from a regular SIM card?

With a regular SIM card purchased from a domestic carrier, you will not be able to use it when you go abroad. If you want to continue using it, you will have to pay very expensive international roaming charges. You will be charged roaming fees immediately, and topping up the SIM card will also be very inconvenient. SIM cards purchased in the country you are visiting are also regular SIM cards.

You can comfortably use this type of SIM card in the country where you purchased it, but you will still be charged international roaming fees when you go abroad. Simply put, a Vietnamese SIM card is for use in Vietnam; a Thai SIM card is for use in Thailand; a Korean SIM card is for use in South Korea...

With an international SIM card, you can always use voice calls, SMS, and 4G/3G services everywhere. The SIM card will automatically roam for free and connect to the network in the country you visit. You can conveniently top up the SIM card using a VISA card. You don't have to waste time buying a SIM card in each country like you would with a regular SIM card.
