Prepaid SIM in Korea: A Complete Guide

What is a Prepaid SIM?

Prepaid SIM cards, known as 알뜰폰 (budget phones), are a popular choice for both tourists and residents in South Korea. They allow users to access mobile services (calls, texts, and data) without committing to a long-term contract.

You can easily purchase prepaid SIM cards at airports, telecom service providers’ outlets, or through third-party vendors without needing a local bank account or contract.

알뜰폰 (budget phones) SIM cards offer two main types of prepaid packages:

1. Monthly Data Package – Ideal for users who need regular data access.

2. 10,000 KRW SIM Package – Perfect for those who only need a phone number.

   
   

Advantages

• No contract or commitment: Prepaid SIM cards do not require long-term contracts, making them ideal for tourists or individuals who prefer flexibility.

• Easy setup and flexibility: Pay only for the services you use and choose from a variety of packages based on your needs. You can register using just your passport, without needing a resident card or local bank account.

• Control over spending: You have full control over your spending. Reload your SIM whenever necessary and adjust your usage as needed.

Disadvantages

• Higher costs and limited offers: For heavy data users, prepaid plans can sometimes be more expensive than postpaid options, which typically offer more data at a lower cost. Additionally, prepaid SIM cards come with fewer customer benefits compared to postpaid plans.

• Shorter validity period: Prepaid SIM cards have limited validity periods for balances or packages. If not used within a specific time frame, the remaining balance or package may expire.
