Allow StarHub Prepaid Users to toggle Data Activation and Deactivation on user's end.
I just learned that there is no way for StarHub Prepaid user to bar all data connection (on the SIM card end) by the user themselves. The user have to manually call the StarHub Prepaid hotline to disable or enable the data every time the user wants to change the settings. Perhaps StarHub can enable this option on the Prepaid App? Other Prepaid competitors have this option. Disabling Data on the phone is still a risky move, because there is still a risk of 'data seepage' where small amount of data might be used on back end phone applications, so the safest way is to disable the data on StarHub's end.
I am looking forward for this feature to be enabled soon, so StarHub Prepaid users can toggle data connection on their app, and may even prevent any accidental data use when there are no data packs purchased.
