Repairing iPhone Purchased in Hong Kong under Limited Warranty in Singapore

Hello Apple Community,

I am facing an issue with my iPhone and seeking guidance regarding repair options.My iPhone's screen is not working. It was originally purchased in Hong Kong.I currently reside in Sri Lanka, where there are no Apple Stores available for repairs.The iPhone is still covered under the Apple limited warranty.I would like to know if it's possible to get my iPhone repaired in Singapore, considering the limited warranty and the fact that Singapore has Apple Stores.

If anyone has experience or knowledge about the process and requirements for repairing an iPhone purchased in one country (Hong Kong) while residing in another (Sri Lanka), I would greatly appreciate your advice and guidance.

Thank you in advance for your assistance and valuable input!
