Dropped Calls & Low Signal - Technical Support From The AT&T Community

Zero Bars or No Network Help

Many things can affect your wireless signal, some will surprise you! Learn about what can affect your wireless signal, and what you can do to improve it. 

Signal Loss - Is It Us or Something Else?

Environmental Factors - Dead Zones

At my sister’s house, there is one spot where I never get calls or text. If I move 5 feet away from that spot, boom, everything works. Sound familiar? This is known as a dead-zone and caused by the environment of your surroundings. Unfortunately dead-zones, in homes or offices, are beyond AT&T's control.

Solution: 

• Move away from dead-zone(s) in your home, near a window or area without electronics.

• Consider using Wi-Fi Calling.

• Know your surroundings. 

Treadmills and Stationary Bikes

I bet you are thinking, seriously? Yes! Almost all electronics emit electromagnetic interference that not only disrupts your wireless signal, but your Wi-Fi signal. The bigger the device, like an elliptical, the more interference it produces. I've seen it firsthand. Did you get a new electronic around the time you started seeing issues?

Solution:

• Move away from the electronics.

• Check out what the FCC has to say.

• Unplug new electronics and test

Time of day

Sometimes, during peak times, AT&T may slow down speed to keep everyone connected. Also, if you see a drop in service, or slow speeds, at a specific time, this could indicate another issue, like equipment around you emitting interference. It could also mean something on your device is causing issues. 

• Check to see if any devices activate around the time you see service drops
• Restart your device
• Check out causes why your devie may be slowing down

Phone Damage

Dropping your phone can damage the components inside. This can affect your calls, texts, and internet experience. Having a case is important and I recommend getting one. A drop can also dislodge the SIM card and permanently damage your phone. 

Solution: 

• Purchase a case.

• Replace your device with AT&T Device Protection.

• Secure the SIM card - Learn How!

• Reset the network - it syncs the phone with the towers.

• Learn about your device's water-resistance rating. 

Rural Areas

Rural areas tend to have weaker signals. One of the reasons, the distance you are from the towers. This means your home may get a weaker signal compared to the center of town. The reason, the tower may be optimized for town center since more people tend to be there. 

Normally, the signal is not an issue in rural areas. But when it is, a key factor to think about is the terrain. If you are in a hilly or mountainous area, you may experience a weak signal, the reason, the signal is being blocked not only by the land, but whatever ground elements are there. You factor in building construction, especially those will metal roofs, you can understand why the signal may be weak. 

Is there an outage or something else going on?

5G Speeds

AT&T may temporarily slow speeds if the network is busy. This means during peak times, you may see slower speeds. We do this to make sure everyone has the best experience possible.
