@scofield,
If you're on a plan, the data rates are 0.5sen/kb.  Also, the way the Maxis bill comes is that it'll charge you for your total usage but they'll credit it back.  Perhaps U wanna double check with 123 Y you're being charged for data usage since 42MB is within the plan you're signed on.

@azim61,
Check out http://forum.lowyat.net/topic/868281 for the APN settings; if that fails, go to Maxis and tell them your problem.  They will need to manually enable "something" on their system.  Forummer nokia2003 reported the same issue and apparently Maxis had to do "something something" on their system; once that was done, he managed to get online *smiles*

PS: Don't ask what "something something" is because we really don't know!

Somethin somethin is ask maxis to enable ur 3g service
