Just wanna share some info here.. There's always pros and cons.. No telco in Malaysia is super perfecto..

I am currently on Celcom RM50 voice and RM68 mobile broadband (limited to 5g but no charges if you exceed).. So far, I never receive any SURPRISE bills.. Infact I'm saving a lot more with Celcom rather than Maxis with the similar usage (both data and voice)

But, yes.. like i said.. there's no prefect telco in malaysia, just yet! The data coverage is like HELL PUAKA ok! I will suck you battery up like puaka.. Hate it so much, but what to do, I prefer Celcom than Maxis.. Especially if you are in KL... wah.. the coverage will go up and down like nobody business... and they oso will lost suddenly.. even the voice call oso will drop or sometimes you can't even make a single call!

And yes.. when the nextwork is rawks.. the speed sangat laju.. love it to the max.. Celcom can works with Celcom.. just sometimes the network.. other than that you will love it to the max!
