Celcom line is sucky and slow. Umobile is faster than celcom
Maxis nvr go for price war with their competitiors. This is because they know that they hv the best coverage and speed.  Digi is damn slow la. Some people are ok with slow speed. So then u may take Digi.

Some people want fast, then its definately Maxis.

Its like Mercedes. U dont see Mercedes lowering their price to compete with Honda or Toyota. Cuz they know they hv a good product. No point compete on price cuz the if compete on price then it will nvr end. U want to lower the price until how low? RM5 for 5 GB?
