In general Telco phones are much more expensive than buying it outright.
What phone are you looking at ?
Also, when dealing with any Telco, always go to their official store instead of their agents. Official stores are called bluecube in Celcom's case. Another way to tell is to see the "dimiliki oleh" at one of the corners of their signboard. If it it not the name of the original company , it's an agent. Avoid it like the plague
