Maxis today started Malaysia's biggest one-day phone delivery operation with the promise of delivering pre-ordered iPhone 6s and iPhone 6s Plus to customers within 24 hours anywhere in Malaysia.

In a statement today, Maxis said over 1,000 phones would be delivered between 12.01am and 11.59pm today.

"Some customers who selected the Express Delivery also decided to take Maxis up on their 'anywhere in Malaysia' promise.

"Deliveries this year have been requested on a boat off the coast of Langkawi, in the interior of Sabah and in Cameron Highlands, to name a few," it said.

Meanwhile, customers could also opt for self-collection under the Express Collection service at any of 40 Maxis Centres nationwide, with a promise of fulfillment within 24 hours.
