This week I switched from a Sprint 4G phone to a T-Mobile 5G.
Connectivity is significantly better, specifically when I am deep inside my apartment building or in an elevator down to the underground garage.
I got a new magic box gold with voice amp from the magic box gen 2. I could not get it to pick up a signal. The gen 2 showed 3 bars. I called sprint and they said the technology the gold uses is not in my area. The reactivated the gen 2. Now I can not get it to pick up anywhere. Makes it to 39% and reboots. I've even tried it on the back porch for testing where my phone gets 2 bars of LTE. Weird.
