Glad to hear that. I have been using Maxis more 25 years with the same 2 number and now 3 additional for the family member. Maxis do excel in their customer service, for example last week the fiber was down around 1:03am. I called up the customer service and they check that there was nothing wrong with the line and ask me to use the backup 4G and open as Case.  And around 4 am they called me up to inform that Unifi was doing some maintenance and they checking me up if the line is up and working again. Kudos to them

Yes they do. Just bind your maxis postpaid with maxis fibre and they will give u at no extra charge

Router is the same, they will give you a USB 4G modem to connect to your existing Maxis router
