i switch from maxis to digi on 2007, until maxis came up with iphone plan. after using it for a month, it all came back.. the feeling of why i hate maxis so much.. poor cs, poor 3g coverage, poor coverage, n very expensive.. to be honest, they were not any better than digi.. at least for me in my area.. now i manage to convince several iphone users(my frens) to change to digi.. but if they are not providing a good service after this, and other telco can, im not hesitate to change from digi.. just dont be too loyal..
