Samsung s4 Notification problem

[quiet77]

I recently changed from singtel to starhub, however I stop receiving facebook, twitter, Most importantly WHATSAPP notification once I lock my phone away for more than 2mins plus. It is as if the mobile data was cut off when my screen is off. Upon, switchin on my phone, all notification pop out all at once. Is any1 or starhub user experiencing this with the new samsung galaxy s4?

Could you have coincidentally installed an app that kill task when phone is in sleep mode?

 

[samson1]

Have you installed any battery savers that cut off data when you off your phone?

Sadly, nope, i did not installed any of these apps, however when i plugged in singtel simcard, it words perfectly fine. Hence i believed is starhub 4G/LTE network tat is behide all these. Any1 starhub user experienced this yet?
