Data plan 38 celcom are super nice to use for iPhone 4 since it doesnt have speed limit but only 1 gb data max. Surf web, twitter, facebook and spme you tube everyday, i havent reach that limit yet. And it Super fast than any other telco.

While 68 data plan, they have speed limit with 5gb data limit. So internet quite fast but i can feel the diff when i change to 38 due to only first month i download lots of apps, use about 4gb data. Then next few months my usage less than 1gb. Facebook, twitter and other social apps didnt consume so much data. So change to 38 data plan. It awesome. Well, i say that it faster than my sis on digi. However it depends on your area.
