I'm wondering why every monthly plan had renew, there's is a 100mb get "reserved" or used?

And it's totally irredeemable. Any expert help to explain?

After system digi upgrade, everytime you use a bit data, it will auto reserved 100MB, you try turn off data a while, turn back on, will show up correct quota
I don understand you want redeem what?

This caused 1 to 7PM 1GB free quota unable fully utilize
As until last 100MB auto reseved, when pass 7PM it will correct itself

Thanks for reply, but it doesn't work as what you said. It is "used". After I finished it, nothing happened.

I not sure what quota you refer to.
Main quota?

Yup, a monthly 1GB subs. whenever it renew, it shows a 100mb is used.

If you got wifi, connect it when plan renew on 12.00am, you will not see any usage
Try off wifi, use some data, eg open browser, send some whatsapp msg using data,
You will see use 100MB, then try off back data, use back wifi, check back usage after 1 min, no more use 100MB, will update back actual usage
I not sure why after digi update system, become like this

Because of this, bigbonus free 1GB 1 to 7PM canno utilize all
Eg usage when reach 950MB, when use a bit data, will over 1024MB, and some portion of main quota
Then after 7PM it will reflect back actual usage

But who will even do that every month....Meaning if we didn't follow your step, the 100mb is trashed?

Nope, even you on whole day long
I will give back after some hour, i not sure how many hour
