There are no services offered to the public, so no need for the map.
I have LTE coverage from the beginning - since I got first LTE router (about two years ago).
They use it for business-to-business links where is better margin.
So never seen this before in my town so thinking it is the new LTE-A offering?
"Phase One of the roll-out of our new LTE-A network is well underway. During this phase, past or existing iBurst Customers qualified for migration (coverage dependent). Three exclusive LTE-A packages were on offer to them, that ranged from 20, 50 and 100 Gig packages.
Enrollment for these Exclusive Packages is NOW CLOSED, and you will be contacted once LTE-A is available."
"We are currently working on the new dynamic LTE-A coverage map and service availability checker. Please note that the LTE-A coverage map and product literature will be available end April 2017."
FYI - Just spoke to an iBurst employee earlier today. I'm in Cape Town (near Tokai) and although my area isn't covered yet, apparently Plumstead has LTE coverage right now - so at least it appears as though they are coming online.
Best way to find out if your area has LTE coverage seems to be dropping them a Twitter DM (direct message) with your name and iBurst account number. That's what I did and got a phone call a few hours later and got some answers.
iburst Lte is not availabe now, and when i asked for date of launch few days ago, they had no schedule. their plan had been delayed for few months now.
