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?
