Why cant customers who have been loyal supporters since 5G home internet service started get tye new gateway with antenna hookups.

I have the same question. The places in my home where I get the best available service don't have tables or shelves close by. The antenna would allow me to place the gateway in a less advantageous spot close enough to a window where I could put the antenna. I've called T-Mobile support many times requesting the either of the new gateways, G4AR or G4SE. Each time I've been told that if I request to swap my current gateway for one of the new ones, what they will send me is the same one I already have. They say they have no way to request a specific gateway. I have also heard that the only way to get one of these new gateways is to be a new customer (even then there is no guarantee). In this respect T-Mobile seems to be trying their best to copy Comcast/Xfinity's poor customer service. Apparently being a new customer is far more valuable to T-Mobile than being a loyal customer.
