I was a Celcom user for the last 4 years , only switched to Maxis cause my Dad kept complaining about the bill shock (due to most of my friends/family being maxis) The cellular network (calling & text) for me was never an issue . Tho I've never fully utilized my 3G nor the EDGE . Would just like to know other forumers experience being on the 3G and EDGE network , as when the 4s comes out . I would like to choose Celcom over Maxis
