Before that, what is the transmitter you were using for receiving analogue TV?  You may be receive digital terrestrial signals if you were able to get TV3 analogue in the past. If there was only 2 channel (TV1/TV2) no chance unless in Lahad Datu and Kudat. Based on the coverage map and DTH coverage prediction, you can only get satellite TV as the only form of TV reception, which can mean up to 9 set top boxes and 9 satellite dishes in your case.

That's..... kinda heartbreaking.  😢 Never mind. 

For your case, you may consider centralised satellite dish, so that multiple MYTV boxes can be connected from the same one satellite dish installed on rooftop by using a cable splitter or multiswitch or something similar. 

Alternatively, the option of having 9 different MYTV Hybrid combo boxes (that supports satellite + terrestrial) across 9 different TV sets is possible though. 

It's better that you get an installer that can directly sell and set up the MYTV hybrid boxes for you, rather than waiting for MYTV's answer. 
Anyhow, because this is kinda "high level" and there are various methods of centralised TV systems, it's better discuss with a technician/installer near you that has the expertise to advise a suitable/better centralised antenna system that suits your premise and budget. 

Or else, 9 individual satellite dishes installed on premise then connected to 9 individual MYTV boxes that connects to 9 individual TV sets across 9 different rooms. 
Sounds kinda messy, eh? I'm not sure the budget wise is cheaper than centralise or not. Maybe cheaper, not sure....
But this is a straightforward method, especially if that 9 rooms are located very far apart from each other, instead of all in the same building block premise.

And yea, unfortunately, it is confirmed that Kundasang is under DTH coverage. 
In layman terms, DTH (direct-to-home) means satellite TV.
And it's very likely that you're able to receive digital TV signals by using UHF antenna.

As for Internet access, does your area has 3G or 4G mobile cellular coverage? Which telco has it, and how's the network performance there? 
If there's no mobile coverage, no fixed internet (fibre or copper) like Unifi or Streamyx, then the only option for you is go for Connectme, a satellite broadband provider.

Because it uses satellite, so it has 100% nationwide coverage no matter where you are in Malaysia, even in deep jungle or in the middle of nowhere.
25Mbps download, 1Mbps upload, 530ms ping (so definitely not suitable for real time online gaming). 

Price? RM98/month for 60GB, or RM138/month for unlimited quota. Both has the same 25Mbps speed as mentioned above. 
Contract? 24 months. 

Hope my info helps...
