guys, my Maxis plan is postpaid and without any data plan. Just wanna ask u guys if my setting is ok, scared it will use my data and later Maxis charge me.

paranoid dy, just now maxis sms me said I reach RM216.

So I went to Security (app) > Data Usage > Restrict
For this part, i
1) disabled all data for downloaded apps
2) disabled all data for apps
3) disabled data for default settings for new apps. (setting icon top right)
Then I went to Security (app) > Data Usage > setting icon (top right)
For this part, i
1) Mobile data limit > Peak data limit being set to 1.00b.
2) Set data usage > didn't make changes to it
3) Restrict peak data usage > on
4) Allow background data > off

for this month this is my usage. duno why maxis send me the sms saying I used RM216.
any1 here without data plan? care to share how to make sure any apps dun suck up data in the background?
From past experiences switching off data will not allow any apps to access the internet. But why not take the Maxis one plan lite, it's only RM78 for 1gb and unlimited call and smses.
