Guys... where else do you guys buy the hard silicon case for BB9790 aR? I can't seems to find it tho... hmm...

Surf Less is out of question for bb. for bb always look into BIS as this is a part of BB.
If you choose Surf Less, it's like you buy a 56K package for your 4G Modem.
Choose BIS, where you can benefit from all of it. BIS package gives you unlimited quota for all BIS features such as BBM, AppWorld, Map, Email, Browser.
Some more what interesting with Hotlink is that they included Non-BIS Quota, which is essential for when you use 3rd party app which is not under BIS such as: Whatsapp,Viber, Line, Youtube.

Another advice is when you go back kampung, when you check your line and it become SOS, no wories, change to 2G instead of 2G and 3G as it drains the battery when the phone changes between 2G and 3G everytime.
What steps did you take to install the OS which failed?

has anyone tried the viber apps? it seems i've tried using the 3g line but it always error.

you're using wifi or bis?

i asked the wrong question.
actually no matter you try using bis/wifi, the error is not on our part, it's on the website.
have you attempted update using the app world and search for update?

can you try again?
use only wifi from home. don't use BIS.
I just attempted on a fully formatted phone and it doesn't work with BIS.
