Nomad
Toque em uma estrela para avaliar
Nomad positions itself as an eSIM app for people visiting multiple countries, covering 165 destinations including South Korea. The service works on fixed data bundles, so you know your cost upfront, but the real draw is the referral system. Each friend you sign up gives you credits toward free data, which means regular travelers can offset costs by sharing the app with friends planning trips.
The multi-destination focus makes Nomad handy if you're island-hopping around Asia or combining South Korea with neighboring stops. The referral rewards lean into how travelers actually move between countries and often recommend apps to each other.
