The Top 6 Reasons Why Your New Smartphone Will Still Drop Calls

You now have a new smartphone, one of the marvels of modern technology. You waited patiently for the moment you could peel back the gorgeous packaging and lift your new device from its cradle to hold and cherish. Becoming the owner of the latest new smartphone is fun and exciting, and it’s something you look forward to every couple of years.

What’s not fun, not exciting, and not worth waiting for are the dropped calls your brand new (most likely expensive) smartphone will certainly experience. So, what’s the deal? Why can’t I make a call with my new marvel of modern technology? Why do I walk down the street and drop a call? Why do I walk into my office and drop a call? Why do I change rooms in my home and drop a call?

Why dropped calls still happen

The more you know and understand about your cell phone and how it works within your environment, the better you’ll be able to find solutions to dropped calls and undelivered text messages.

We all understand that if you are in the middle of nowhere, with no cell towers nearby, that you will not have enough signal to make a call. But let’s assume that you are in an urban area with cell towers all around you. Even with local cell service, potential causes of cellular reception problems can include:

  1. Signal strength
  2. Carrier frequency
  3. Building materials
  4. Cell phone cases
  5. Shadowed and fading areas
  6. User load on cell phone towers

Signal strength

Naturally, signal strength is the key factor in dropped calls. Cell phones require a minimum cell signal strength to maintain the connection with a cell tower; signal strength below a minimum threshold will result in a dropped call.

Carrier frequency

One little-known fact is that the cellular frequency used by your carrier may be contributing to dropped calls in certain locations.

You and your friend could be standing next to each other, each with the same, brand-new smartphone, with one of you using Verizon and the other using AT&T: Your friend may be talking with no problems, while you’re dropping calls. This is because Verizon and AT&T use different frequencies, and the strength of your cell signal is different than your friend’s.

There are five main frequency bands used in cellular communications:

  • 700 MHz LTE
  • 800 MHz Cellular (the earliest cellular frequency still in use)
  • 1900 MHz PCS
  • 1700 MHz AWS (uplink)
  • 2100 MHz AWS (downlink)

The higher the frequency, the shorter the wavelength. Higher frequencies with shorter wavelengths (1700, 1900, and 2100 MHz) have more difficulty penetrating building walls and have less broadcast ability (free space loss) than lower frequencies with longer wavelengths (700 and 800 MHz). Given the same cell signal strength and power levels, 800 MHz will broadcast through open air about twice the distance of 1900 MHz.

Building materials

Dense or reflective building materials can block cellular frequencies and cause cell phone reception problems. If you’re inside a building made from one or more of these kinds of materials, you’re more likely to have inadequate cell signal:

  • Concrete
  • Steel
  • Stone
  • Large logs and timbers
  • Low-e glass and other types of glass tinting and films
  • Metal roofs
  • Some types of stucco

Cell phone cases

The premium case you bought to protect your $1,000 smartphone could be causing your cell signal reception problems.

Avoid using cell phone cases with metal components. Encasing your cell phone in metal can create a mini Faraday cage and block reception.

Shadowed and fading areas

You’re probably aware of certain places where you know you’re going to drop a call. This “dead zone” on a city sidewalk or at specific place in your daily commute. You tell the person on the other end, “I’m coming up to a place where I’m going to drop you; I’ll call you right back.”

Most likely these areas are shadowed by something like a building, a hill, or an underpass. Areas where cell signals are blocked and shadowed can exist anywhere: in cities and suburbs, in rural communities, and along highways.

User load on cell phone towers

Another little-known fact is that cell phone towers have limits on the number of simultaneous users they can support. Sometimes cell towers get overloaded; calls in progress start to drop, and users can’t make new calls.

User load problems typically occur during large freeway traffic jams or other large gatherings of people in unexpected places.
