i am in kuantan and been using maxis for past few months. 6 months or so... faced a few times of unstable wifi.. yes wifi only where the wifi disappeared. and now using my custom router and upgraded to 300mbps.. the speed maintained, unlike unifi sometimes 100mbps sometimes 300+mbps ( was previously using unifi). so overall maxis ok...

and in case you dont know, you can combime with maxis postpaid and your maxis postpaid and all the supp lines will become unlimited too... and you will get a 4g backup dongle for your home too...
