How does cell phone coverage work? I don’t think any carrier is close to 100% coverage in the US. Are the parts of the US where my cell phone won’t work at all depending on my carrier? Are cell phones able to connect to other carriers towers?
In: Technology
Towers have a range. The higher the bandwidth, the shorter the range. It is not practical to cover the entirety of the massive, mostly empty parts of the US.
Your phone will still work, just won’t be connected to the outside world. However very importantly, even if your phone says you have no signal, you can still phone the emergency services, it allows your phone to use reserved military satellites and bandwidths to make the call. So always try to call 911 even if it says no signal.
