The INVCALL Cell Phone Signal Booster for Home is designed to enhance cellular signals for homes up to 7,000 sq ft, supporting major U.S. carriers like Verizon, AT&T, T-Mobile, and Sprint. It’s compatible with 4G LTE and 5G networks, making it a versatile choice for improving connectivity.

Many users have reported significant improvements in signal strength. One reviewer noted an increase from 1-2 bars of 4G to 3-4 bars of 5G in their home office. However, performance can vary based on the location of nearby cell towers.

Installation can be tricky for some. A user living in a bungalow struggled with the recommended 27-foot spacing between the exterior and interior antennas. They found the provided 30-foot cable insufficient and suggested that at least 50 feet would be more practical.

Despite these challenges, the booster has proven effective in rural areas and large structures. One user in a steel Quonset hut saw noticeable improvements after installation, though they had to supplement with additional cabling and boosters.

The booster comes with a high-definition LCD screen that displays real-time status updates, which users found helpful for fine-tuning antenna positions. The included window entry cable was also praised for its convenience.

However, some users were dissatisfied with the accompanying app, which requires detailed purchase information and was perceived as invasive. An open-source alternative was recommended instead.

Overall, the INVCALL Cell Phone Signal Booster is a robust solution for improving cellular reception in challenging environments. While it may not turn a dead zone into a signal paradise, it significantly enhances usable signals and is worth considering for those struggling with poor connectivity at home.
