I'm a developer in South Korea working on a service that integrates PayPal through a payment service provider. I've finished all testing with PayPal's sandbox accounts, and everything runs smoothly there. However, when I transitioned to the production environment, I hit a snag. It's challenging to perform real PayPal payment tests from within Korea, especially when I'm looking to simulate transactions from foreign users or cards. Many of these transactions either get blocked or don't accurately reflect actual international payment behavior.
To properly validate the production flow, I need to test with a foreign-issued card (non-Korean BIN) under realistic conditions.
I'm wondering:
1. Is it feasible for a non-resident to obtain a foreign-issued card (like one from the US, EU, or Southeast Asia) for testing?
2. Are there any fintech services (similar to Wise, Payoneer, etc.) offering virtual or physical cards with non-local BINs to users outside that region?
3. How do other developers usually manage this stage of testing for cross-border payments in production?
Just to clarify, I'm not trying to bypass any compliance or restrictions; I just want to replicate authentic international payment scenarios more reliably before going live. Any insights or real-world experiences would be greatly appreciated! Thanks!

Be cautious with using a real card for testing, as it can violate terms of service with most payment processors. Testing with real transactions, even in limited amounts, could be considered risky. Most developers I know either collaborate with foreign users or utilize sandbox environments extensively prior to going live.
I see your point about the risks involved. Given that it's quite common for developers to test limited real-world transactions, do you think many teams typically engage friends or users abroad for these tests?
