Learn some SWOT
It's really pissed me off due their worst network and unworthy sales, example "Rm5 6Gb for 2days" what the f is that? At least givelah extra 3days, lanjiao! Everything comes up with expensive prices but the time duration so short. Then, network huh.. After the end of the covid, the network started became worst for my experience la, when I call my family using WhatsApp always disturbed by reconnecting and weak network make the voice unclear to hear. I guess you should go study the SWOT.
