For the customers who subscribe to the plan with their own iPhone 5s, the monthly fee for the 5GB plan with a 24-month contract term is HK$258.
However, customers may choose to pay a monthly fee of HK$448 for the same plan and get a free iPhone 5s, which sells for HK$5,180 at Apple stores in Hong Kong.
The 5GB monthly plan includes 2,400 voice minutes. After those voice minutes are exhausted, extra charges apply. For up to 300 extra minutes, the charge is HK$0.15 per minute; and from 301 to 1000 minutes, the charge is HK$0.02 per minute.
The 5GB monthly plan also includes free intranetwork SMS, which allows Smartone customers to send free SMS to other Smartone customers.
