LTE?

I have the HTC one and am on a topup 400 contract with vodacom. How do I check if my phone is LTE compatible and activate the service.

So far I have changed my APN to lte.vodacom.co.za and the speeds have improved, around 7.8/3 mbps down/up respectively now. Do I need to buy the "Broadband advanced" data bundles?

Also is there a map with LTE coverage in cape town?
