But before find solutions to improve cell phone signal for your car, let’s learn about what causes poor reception and drops your calls.


What causes bad cell phone reception?

Many different causes can lead to weak signal in your car. The most common causes include:

Distance from cell tower

In a remote area, distance from a cell tower has the greatest impact on signal strength. A cell tower has a certain range of signal coverage. The farther you’re from the nearest cell tower, the weaker the signal strength you will receive in your car.

An increasing number of users and phones

A cell tower also has a users capacity, which usually allows a limited amount of users and phones for phone calls and data simultaneously. You will receive slower service and data speed with an increasing number of devices connecting to one source.


Obstructions take an important role in weakening the signal transmitting from the cell tower. They can be categorized into construction material and organic materials. Construction material such as aluminium, steel and glass of the exterior of your car disrupt 3G, 4G LTE from reaching inside your car. Organic material like mountain, hills, trees or other dense plants also has an impact on weakening signal strength.

In a remote area, physical distance from a cell tower is the biggest factor for poor signal reception in your car, causing dead zone and dropped calls. In the urban area, interference and more users and devices are always the culprits for unreliable service.
