How do I obtain mobile service where there isn't any?

We’ve become reliant on our smartphones and anticipate excellent cell coverage everywhere we go. How were we to fail? They are tiny, mobile computers that support our ability to communicate. There isn’t a flawless cell phone signal, though. Cellular dead zones can be found all throughout the world, most frequently in rural areas and within residential and business structures.

Cellular dead spots in places where there is no signal for miles can, sadly, not be fixed, however dead spots in enclosed areas can be mended.


What's a Cellular Dead Zone?

Cellular dead zones, to put it simply, are places where there is no cellular signal, either due to signal blocking or because the cell phone tower(not published) is too far away.

What Leads to Dead Zones on Cell Phones?

The radio frequency (RF) signals that cellular towers emit help cell phone signal. A cell phone dead region is generated when the RF signal is too far away or is obstructed by objects. The primary offenders are:

  • Distance from a cell phone tower: RF signals can only go so far; the farther you are from a cell tower, the weaker the signal gets until it finally vanishes.
  • Topography: Natural signal obstacles include hills, mountains, ridges, and vegetation. They have the ability to reflect or absorb signal waves, blocking them from reaching your phone.
  • Building Materials: Metal, low-e glass, concrete, and brick are the main causes of poor cell phone reception indoors. These materials make it difficult for signal waves to get through, which results in patchy or nonexistent cellular coverage.
  • Tall Buildings: In regions with plenty of tall buildings, the cellular signal can suffer significantly. Buildings not only obstruct RF signals, but they also cause reflected signal waves to clash with one another, weakening and changing direction.
  • Weather: Snow, rain, and humidity can all reduce cell phone signal strength. The signal is weakened as a result of the RF energy being reflected, refracted, and absorbed by the air’s water vapor.

When an outside signal is already present, solutions for in-building cell phone dead zones

When there is cell service outside, it is very simple to fix the lack of coverage inside of buildings. Buying a cellular signal booster or moving to the top local cellular service provider are two options.

Cellular Signal Boosters

Cell phone repeaters(not published) and amplifiers, commonly referred to as cell phone boosters, are incredibly effective at boosting cellular coverage inside of nonexistent cell service buildings.

They function by rebroadcasting your outside 5G/4G/LTE signals (whether they are strong or weak) inside specific rooms of your home, place of business, or vehicle for all cellular devices and carriers. They also function in reverse, picking up and boosting the outgoing signal from your mobile device before sending it back to the cell phone tower.

A signal booster can therefore be useful if there are spots in the house where the signal flickers, such as near windows or while sitting on the back porch. If you can only make a connection while standing in your driveway, the problem might be anything as simple as obstructions like construction debris, trees, mountains, or even bad weather. If so, a signal booster can quickly and effectively deliver you the service you require.

Do Signal Boosters Function Even When There Is No Outside Signal?

A sad No. Instead of producing cellular signal, they enhance it. However, the absence of bars on your phone does not always indicate that there is no signal at all. Cell phone bars are arbitrary, after all.

Signal boosters are significantly better at getting the closest signal because they have stronger antennas than cell phones. Therefore, even if it seems like your phone can’t receive a signal, a network extender might still be able to look for a cell phone signal and then increase it to the speeds you require.

How can I tell if I have signal outside or not?

It is recommended to measure your signal in decibels (dBm) rather than in bars in order to get the most accurate impression of how much signal you are working with. For Android, applications like Network Cell Info and LTE Discovery may make dBm monitoring and measurement simple and immediate. Sadly, there aren’t many trustworthy dBm measurement apps for iPhones.

Turning on test mode is the most effective technique for the majority of iPhone users to access dBm data. Simply dial *3001#12345#, and the dBm reading will show up in the top left corner or under the rsrp0 or RX AGC0 tabs on the dashboard (depends on iPhone model). Unfortunately, because of the iPhone’s processor and cellular carrier, test mode doesn’t function for all iPhone users. As an alternative, you can access a decibel-reading feature in Settings if you have an Android phone.

The ideal range for an outside signal is between -50 and -80 dBm. You are likely receiving 1-3 bars of subpar mobile reception if your dBm value is between -85 and -105 dBm. Anything less than -110 dBm is either dead or severely patchy.


A signal booster can typically reach that far mobile signal with the right external antenna setup. However, even with the greatest signal booster for rural locations, you’re probably going to have less coverage because of the strength of your outside signal.

Change mobile providers

It can be very time-consuming and inconvenient to change carriers. However, it can be worthwhile if there is no service in your neighborhood. Different phone providers own and manage a large number of cell towers. Cellular dead zones may exist because the nearby cell phone towers are not run by your carrier.

You can use a variety of websites and applications to locate the closest cell towers, including Cell Mapper, Network Cell Info (for Android smartphones), and OpenSignal (for Android and Apple). Alternately, go old school and find out which carrier your neighbors use.

When there is no signal outside, how can I get cell signal inside?

When you’ve exhausted all other possibilities and found that your nearest cell tower is simply too far away, it could be time to activate Wi-Fi calling(not published) or consider femtocells (also known as microcells). However, unless you have access to a dependable internet connection, there isn’t much you can do without an outside signal if you’re fully off the grid, such as in the middle of a forest or at the base of a mountain.

Wi-Fi calling

Try using Wi-Fi calling if you have a dependable Wi-Fi connection. You can communicate verbally and textually using Wi-Fi calling rather than a cellular network. Many people who have poor or no service inside or outside their houses utilize Wi-Fi calling to increase the quality of their calls and their ability to send texts. Through the settings of your phone, you can turn on Wi-Fi calling.

Apple iPhone -> Settings -> Phone -> Wi-Fi Calling

Android -> Settings -> Connections -> Wi-Fi Calling

Microcells (Femtocells)

You might think of femtocells as your own little cell tower. Your broadband internet connection is transformed into a 5G/4G/LTE cellular network for your data-enabled devices by these network extenders.

Now what? You require use of the previously specified broadband internet connection. Unfortunately, satellite internet—which is a common* choice (or, might we say, last resort] for extremely rural areas—rarely provides enough speed to enable a femtocell.

The device will broadcast a workable mobile signal into the targeted area once it has established a connection with your internet. When you place a call, the signal goes across the internet, enters a FEMTO gateway, and is then sent to the recipient. Multiple femtocells may be required to improve the signal in several locations, which could (and frequently does) slow down internet speed.

The only way your out-of-town guests can reach your signal is if you both have the same network provider because microcells and femtocells are likewise carrier-specific.

Methods for Spotting Dead Zones

The worst time to discover you’re in a cell phone dead spot is after moving into a new house or after missing a crucial call. Maps of cell phone dead zones are excellent resources to utilize in order to check for dead spots beforehand and prevent your cellular signal from betraying you.

Every cellular service provider offers a map of their coverage area for mobile devices, but as we all know, these maps are not entirely accurate. Maps of cell phone dead zones can show you where your carrier’s coverage is actually lacking. You can get ready for upcoming trip plans, lengthy commutes, and prospective real estate purchases by being aware of the dead zones.

A great website called will show you places where mobile phone coverage is sometimes lost, where network congestion occurs, or where there is no cell phone service at all. Real users who report wireless dead spots throughout the globe compile the data.
