If you're opting for maxis you have to know that the 20GB is not general internet. Its 10 GB + 10 GB, meaning that you have 10GB for the whole month, and 10GB for weekends, which I usually dont finish. But my main 10GB always left about 500MB, cause before refresh I will spam kao my internet. hahaha.. Im also using digi postpaid u28, so far coverage is good. But at my work place, around atria area sometimes no line. LOL.
