Thinking of porting out from maxis , anything else that I should know before  porting out ?

Line is too bad , getting overcharged. I was told to infrom banks if I switch telco and retain the same number ,c ould someone verify ?

Been with them since 2005 as prepaid , and then 2007 changed to postpaid. Service is going down hill , they use to be good , but now lots of drop calls , Internet connection is unstable (you used to get 10Mbps on 3G , but now it is like 1Mbps and sometimes its like 400-500Kbps). Things have just gone bad

I thought it was my phone , changed phone as well and it's still downwards.

End of this month , I'll be porting out
