did you cut your sim from normal to micro sim size?
that could be the reason. better change to an actual micro sim from celcom center.

Why dont you tell them instead of changing of new phone why not let you upgrade to htc one.   You can wait another 2, 3 weeks or should that be downgrading?  Hmm.. htc.. might consider as my next phone if s4 is a crap..

I think he just got the phone so they r willing to swap. If it is with him longer then I doubt even htc will swap that.

Removable battery is much better.
My Butterfly freeze and I cannot do anything at all.
Wait till battery finished and the phone finished also. Never wake up.
Now waiting for RMA...lolz

debit card also can

what you mean without name at the card ???

no need, as long as you buy the app using that gmail, then you sign in that gmail on any android device you also no need buy anymore
easier say, buy 1 time, can install many times you want, and also install on any device you want as long as using that gmail

off course don't have name
only got the 16 number, and expiry date @@

Because nobody else in this S3 thread uses a GT-19305 and lives in JB/Singapore.

Coincidentally, samdroid, samsungxp and stahl all use GT-19305 and live in JB/Singapore.

How I know?
SamsungXP keep bising he live in JB work in Singapore so got use for his S3 LTE
Samdroid said himself he live in Singapore.
and Stahl.. Uploaded a screenshot of his home screen with the LTE line and location stating Singapore. Genius or what? I think if this fella play hide and seek, he will be the easiest person to find!

When Samdroid appeared, SamsungXP disappeared, maybe kena kidnapped by Gnomes kut.. Then when Stahl appeared, Samdroid disappeared pulak. Maybe the Gnomes like to kidnap lowyat users whose name start with S.

Quick question, can I get the official Samsung extended battery anywhere here in KL? Been waiting a long damn time for the thing.
