For mobile phones usually DHL.
Not sure also it's better if you ask the seller directly. But again nowadays even the sellers themselves can't pick which courier to enabled edy all random depends on Shopee auto pick system.

Sure boh? When?

RIP la after 4.4 sales it's gonna get worse when most parcels get dumped here.

That's why for urgent stuff I don't dare to buy from online store. Let alone from Shopee with courier delivery getting crappy nowadays.

Still doesn't make J&T God sent. More like those who puja puji J&T will now understand how it feels like when your favourite courier of choice been taken away from you.
All auto assigned to shitty one instead.

My area J&T always been shit but Shopee all auto assigned my parcels to them since last year with exception of ShopeeMall and overseas shops. Hence why I no longer buying from locals there. Already lost items and asking for refund was real PITA. When I asked sellers to turn off J&T from courier options they refused when parcel missing they blamed me for not waiting another few weeks.

Now they themselves can't even pick their beloved J&T anymore to drop their stuff I'll say padan mukak.
