Difficulties You May Meet Buying Prepaid eSIM
Sure, here are some difficulties you might encounter when buying a SIM card in South Korea:
- Language Barrier: Buying a travel SIM Korea may be difficult if you don't speak Korean. Most of the documentation and communication with the providers is done in Korean, and many kiosks may not have staff who speak English.
- ID Verification: You must have a valid passport and a local phone number to buy a SIM card. The process may be even harder if you do not have a local phone number or address.
- Limited availability: There are few places to buy SIM cards, particularly in rural areas. This means you may have to travel further to find a kiosk or wait until you reach a major city to buy your SIM card.
- Activation Time: Activating a prepaid SIM card can take several hours. This means you may have to wait a while before using your new SIM card.
- Confusing plans and packages: Many different packages and plans are available from various providers, and it can be challenging to figure out which one is best for your needs.
- High prices: Compared to other countries in Asia, including neighboring Japan and China, SIM cards can be more expensive, so you should consider this when budgeting for your trip.
