I just recently started to use mobile data, in first I start with a monthly plan, which is feet in, but later I changed to a weekly plan, but I can't use it properly and set the data limit to feet it...
Also, because of the change before few days of the end of the previous plan the previous usage is still there, and I can't use my data without turning the traffic on, and can't use the data limit feature too...
I remember being able to change the cycle before, and being able to clear data, but now I don't see it...
