5G Home Internet vs. phone data speeds

I agree 100% with "formercanuck" the phones do have priority over the fixed broadband gateways due to the nature of cell phone calls and roaming from tower to tower. Testing with a cell phone vs. the gateway can be rather deceptive. From one manufacturer's cell phone model to another there are often huge differences in the radios in use. If you buy a premium cell phone you are getting better tech than the average cell phone so it is not a comparison that will lead to conclusive results. 

The service in one area vs another can vary greatly and it seems to come down to higher density urban areas with heavier user loads requiring the use of bandwidth throttling due to load. T-Mobile may be expanding their network but it seems to me the cells are still often loaded heavier than is optimal for service to be what users are/were expecting. The ONLY way you will know how the T-Mobile solution will work for you in your location is to try it out. Exercise the solution as much as you can during the trial period to profile proper expectations. You can read threads on Reddit, here and other forums and get a better idea as to if it is what you will find satisfying or not.

T-Mobile runs a IPv6 network and a 464XLAT solution so don't expect NAT and port forwarding controls you might have become reliant upon without a VPN solution. Games that rely upon UPnP are not going to be functional on the T-Mobile solution. Go read the FAQs on the T-Mobile pages. Don't be blind sided by not researching the details. I know the T-Mobile home gateway solution can be pretty darn great in some markets. Here we are in a rural area with n41 for the data load and it is very good. We started out with n71 delivery and then they upgraded the cell to n41 and the speeds just about doubled. Still the speeds vary depending upon the time of day/night and load. Weather can also be a factor. Well, there are a number of factors but if your location is close to a cell source and good clear delivery it can be pretty good. In higher density markets where user load is heavier that equation may not work for you.
