Home 5G Cell Phone Signal Booster | 4G LTE Verizon, Straight Talk Band 13 Cell Signal Booster | Boost 5G/4G LTE Data and Calls | Cover up to 4,000 sq.ft | FCC Approved

We bought this booster because we don't have a T-Mobil signal inside our house (about 2,300' sq ) but outside is 2-3 bars. The device works as advertised however we have issues. The signal inside the house can be full and we still don't receive calls about 1/2 the time someone calls us and when we do connect it often drops off even with a strong indicated signal. This said it is better than no signal. Also I am not versed enough to know if these issues are T-Mobil issues or the booster. We are spoiled with good phone service generally so in some regards I don't like wining but this booster isn't cheep.
