I ordered a signal booster from T-Mobile due to poor signal in my Manhattan apartment. They sent a unit and I had no trouble setting it up. Everything seemed to be working fine, but there was no improvement on my devices. Still 1 bar, which drops out when walking around the apartment. Tech support did some superficial flow chart troubleshooting and quickly opted to send out a new unit it exchange for the current unit. The new unit arrived, same result. Everything seems to be functioning properly except there is no signal improvement. It's as if my devices don't see the coverage unit to connect to it. I called tech support back, the did the same superficial flow chart troubleshooting and again, offered to replace the unit. They assured me they will test the unit before shipping it, just as they did the second time. Since I don't seem to be getting anywhere with the Kolkata call center, I thought I would ask if anyone in the US would have some first hand experience why this is happening. I have no reason to expect that the third unit they send will have any result other than the previous two.
Both the window units were able to achieve 2 bars of signal and the LTE light was on. The coverage unit has an 8 on the coverage range. My phone maintains 1 bar. Both boosters were properly registered with the correct location of use.
