Avoid Maxis at all costs.
Their customer service will raise your blood pressure. Their hotline staff will only dodge your complaints by saying their technical team will call you to update. No one will call. When you counter that none of their technical team had called for a week, they will change their reply to "they will call when the problem is fixed". And what is the estimated time for the problem to be fixed? Don't know, they are still looking for the problem. And the hotline staff will say that the technical team had updated something into their report system, but she cannot interpret what it means.
In other words hotline staff and technical team will jointly give you the runaround. And each time you call again, you'll get a different staff for you to tell the whole sad story again. Your blood will boil.
The above is personal recent experience as a mobile broadband subscriber.
I've been a Unifi user for 30 months. Only had to call their Customer Service twice. In both cases problem solved on the spot. Mine is 5Mbps but that is plenty. Main use is torrent DL 24/7 and I'm getting 1080p movies (~10GB size) faster than I can watch them. No cap, no throttling, self recovery when speed drops. At peak times speed will drop but I get >600KB/s (sustained) frequently. How to complain when overall I get >30GB of torrent DL per day.
No matter how attractive Maxis' package is they will shortchange you later and you're tied with their contract. Once again my advice is: STAY OFF MAXIS.
