MultiSIM with data sharing still available. I subscribe to 1 primary and 5 secondary last year around 20/12/2012 and received the SIM cards last week. Just activated today. According to CS, my primary line has unlimited data at RM 99 per month and it is a corporate package.

I faxed in a request to their corporate department. Walk-in always give wrong info.

Primary SIM: RM 50 (commitment) + RM 99 (data)
Secondary SIM x 5 (RM 15 per SIM sharing everything from primary SIM)

From what I gathered, Maxis only accept corporate application with a valid company registered with SSM.

Finally, all my 5 secondary SIM have data shared from primary SIM.
