It's highly unlikely. South Korea is a fantastic destination, but it's not typically included in 'free roaming' zones for US or Australian carriers. While some plans might offer international roaming, it usually comes with significant daily fees or very limited data allowances that quickly become expensive. For instance, many US carriers charge $10-15 per day for international roaming. EastESIM provides a dedicated, affordable data solution for South Korea, connecting you to powerful local networks like SK Telecom or KT without the worry of unexpected roaming charges.
