for confirmation, i just called apple saying i bought iPhone 8 from apple store SG and now got problem. can i sent it at malaysia? she asked for imei number for call report purposes before asking my model no (the short one). then she said no problem i can send here in MY.

then i just asked what's the actual policy, she said actually now apple has international warranty for country that has apple store. for country like malaysia, the authorised service center will send the phones to SG if let say the parts is not available in malaysia. However, normally for SG set shouldnt be a problem because SG and MY always share the same parts.
i think if the warranty is denied, the culprit might be machines or these 3rd party authorised sc. we should always consult apple and ask them to step in if the sc refuse the warranty claims.

true, but can be the 3rd party authorized SC has different policies than apple. normally they have different level of partnership in which some levels dont have to follow 100% the policies set by the principle. i dunno. but as long as people know they can contact apple careline in case of any issue, perhaps these 3rd party SC can assist sending the overseas set to SG.

last time i bought imac from apple my online store, they still need to send it to SG when i sent it for broken hinge. i guess our local SC has very limited parts thus they 'prefer' to reject warranty claim at the first request.

No warranty in Malaysia
