Signed up for their RM28 mobile internet almost 3 weeks ago, been using it on my android phone without problem.. until last Saturday I found myself couldn't access apps (that requires a google acct, e.g. youtube, facebook) anymore. 3G was on and no prob if using browser, but it just won't allow me to access those apps anymore. This is the error i received: "Can't establish a reliable data connection to the server".

Thought it's my phone/android problem so I tried various methods including removing Sim card and putting it back again, even performed a factory reset!

It's the same.. so changed the Sim card to Maxis and the problem just disappeared! I managed to add my google acct and as thought I could change back to using Umobile sim card, the problem just emerged again.. now i'm pretty much confirmed it's Umobile causing this problem!

I spent few 4 good days figuring all kinds of workaround including a factory reset only to find out that it's all a waste of time! Trying to call Umobile customer service for days but no one's answering.

Now, what should i do? Switch to Digi? or keep trying until someone answers my call... Anyone here has the same kind of experience with Umobile?
