HCMC neighborhoods/buildings with fiber optic internet?

Does anyone have any suggestions on neighborhoods or apartment buildings in District 4 or 1 that have the ability to use Vietel's fiber optic internet packages?

I think they cover a wide set of building in D1. Best is to check the opposite (Select an appartment you like, and check if Viettel is available).

In Horizon Tower, it seems doable. (I'm migrating from FPT to Viettel)
