5G home internet keeps dropping

We had the same issues with our 5G gateway device. We had only 2 bars which was supposed to be enough for a signal, however, when we had a signal our service was extremely slow and it was constantly dropping completely. We contacted customer support, went through all the troubleshooting with engineering (checking the signal, switching towers, moving the device around, etc). Finally, requested T-Mobile reactivate our previous device (the 4G LTE small white box).  Solved the problem instantly, strong signal, good speed, no drops, no problem streaming. After reactivating and connecting the 4G LTE Gateway the tech essentially admitted that the new 5G service is essentially a work in progress and isn't up and running smoothly.  He said they are working on it and would contact us to upgrade our hardware to 5G when it was functioning properly in our area. Hope this is helpful.
