Entering the Korean market requires SMS verification. But which is more stable: virtual or physical numbers?
Virtual numbers are temporary, while physical ones are real SIM cards. The former is cheaper; the latter more stable.
Physical numbers, tied to real identities, face lower ban risks. Virtual numbers may be flagged for reuse.
Virtual numbers are easy to get and cheap but may have delays. Physical ones are costly and complex to activate.
South Korea has strict communication rules. Physical numbers offer better compliance assurance.
For short-term projects, use virtual numbers. For long-term business, go with physical ones. Check provider reputation too.
In short, there's no absolute best. Weigh stability, cost, and compliance based on your needs. Test small first.
