Unifi Mobile has its own 4G LTE network which runs on Band 5 (850MHz). For areas that are not covered, it will roam into Celcom’s 3G/2G network. Since their data quota is split between LTE and LTE/3G, you’ll need to be within Unifi Mobile’s coverage area and have the right device in order to maximise your usage. In case you’re wondering, Unifi Mobile is supported on iPhone. You can view their coverage map here.
