i'm having the same problem, keeps charging me RM0.83 for data roaming though i've switched off data roaming.

@Hotlink, I've emailed to your greenlane@maxis.com.my previously (and now) but never get any response. it seems this problem has exists since few years back but yet to be solved till now...

kindly advice ASAP as my credit is running low and will be out of credit by next week if this issue keeps repeating.
