CS told me after this unlimited plan funished, continuous to use for old clients will HKD 296 for 6GB only. Also, I can choose add money to get unlimited plan. But price will UP UP,UP. Since I saw some ching said can (without contract) to use the unlimited plan in original price HKD 220 only. That's why I ask for help is it Ok or not , any ching had experience to share its work or not.
