for U Mobile, you can make it more than 6gb actually, up to 12gb. But it requires careful initial planning(which cannot be done now atm).

still the same thing, get 6 sim, but perform the initial reload on these date:
3rd
8th
13th
18th
23rd
28th

so let's say for the 1st one, your validity should be from 1-5th, on the 1st and 2nd you'll use the current month's 1gb, then from 3rd onwards you'll be using the next month's 1gb. Repeat the same thing for the rest and you'll get 12gb.

I'll just take the 1st one as the rest are of the same concept.

On 1st of each month, you reload RM5 so your validity is until 5th of that month.

Your quota resets every month and it is based on your first RM10 reload date.

Assuming that your initial reload is on the 3rd, so if you use your data before 3rd then you are considered using your current month's data, on 3rd onwards then it will be next month's data because your quota renews every single month.

so taking that into consideration,

on the 1st-2nd day you will be using the current month's 1gb data, 3-5th = next month's 1gb data because the data renews on 3rd, so effectively you have 2gb to use over 5 days(or if you want to be more precise, 1gb for 2 days and 1gb for 3 days)

Usage of up-to 12GB with 6 SIMs is possible on a bi-monthly basis. You skip reloading this month and reload only next month to use this month's last 3 days quota plus next month's first 2 days quota .....

Best of luck
