I woke up in the morning and check my data usage for yesterday. And i was in shock when i saw the data usage for this morning exceeded 1GB. I slept before 12am yesterday, and my phone was connected to my house wifi. How can i use 1GB of data while i am connecting to my home wifi and i was asleep. I am really upset with starhub performance. I was unable to evev connect to 3g network yesterday whole day. And they gave me a shock this morning. Bravo! Welldone.
May we check if you're using iPhone if yes, please check under Mobile Data if Wi-Fi Assist is turned on?
