2 Buy a Femtocell
A femtocell is a device that also enhances the signal in your house, albeit in a very different way. These devices connect to the internet and then create their own Wi-Fi based connection, which they pair to a specific phone in range. If you don’t have the option to enable Wi-Fi calling, a femtocell is the hardware version of the solution, and can be very useful if signal strength is particularly horrible or nonexistent at home.
The issue with femtocells is that they are becoming harder to find as Wi-Fi calling and other solutions have grown more popular. Some major carriers like Sprint, Verizon, and T-Mobile still offer them, but you may have spend a little time looking. Here’s a full list of the femtocells that are still sold. Remember, you have to match the femtocell with your carrier!
