I received the SMS too.

I don't think there's any cons because:
-save RM2
-extra 3gb data
-contract period still remain the same as iValue contract.
-unlimited call & sms to all network compare to current iValue 1 plan 333mins(all telco), 1000mins(maxis), sms(maxis)

I called just now to upgrade it, waited 10 mins for the CS to pick up and CS explained everything and I decided to change it. Besides that, I do have a sup line
Surfmore 75 with 5GB data and I subscribe it to the data pool and get extra unlimited call & sms at lower price.

There's no contract to the sup line and CS did mentioned that there will be some pro rate due to the billing cycle. Need to wait for the bill then only can give the final comment.
