In a perfect world, our mobile phones can work normally all day long. Every time we enter a number, there will be a clear voice answer: "Hello?"

However, the real world is a labyrinth of obstacles: thick walls, metal frames, competing signals, distant signal towers and entire skyscrapers block our way.

Driving behind a mountain, you will scream in static electricity until the signal is finally cut off. Delays and echoes can make the call more frustrating, and most of the time your environment is the culprit.

There is an insider technique that can work miracles. Tap or click here to learn a secret smart phone trick that can boost your weak signal on the go.

Ironically, many people struggle with poor signal at home. Your house-once the only reliable place where you can make calls-may be full of signal-silencing structures and distracting devices. If your home cannot provide a clear signal to the nearest cell phone tower, you will have problems because you may not move quickly. Again, what if your house is a huge blind spot? Shouldn't you call from the living room?

There are at least three ways to keep the signal strong. Improving your mobile phone service is a task of trial and error, and unless you try, you can’t tell whether these technologies are effective. In the end, you may only need to change the carrier. However, if you are willing to troubleshoot, you may find yourself having a clearer conversation.

Also called a "repeater", a signal booster does just that: it boosts your cell's signal. Place the device in a well-received area of ​​the house, such as a window sill, and it will extend the stronger signal to other parts of the house. Some repeaters also have external antennas that can be installed outside.

Boosters are a bit expensive; some carriers sell reasonably priced models, but this is not always ideal, because boosters are usually only suitable for that carrier’s signal. Therefore, if your family or friends use other operators and their signal is also weak, it will not help them.

Boosters produced by third-party companies like zBoost or weBoost can work with multiple operators. However, you may need to pay this fee out of your pocket. At the low end, these gadgets get you back about $200.

In addition, if you want higher-speed 4G coverage, you can expect booster prices to soar to $300 or more. However, 4G is the main advantage only when you use your mobile phone to connect to the Internet. If you already have Wi-Fi at home, you can use your home Internet connection on your phone instead of the more expensive 4G booster.

Femtocell is also called "Micro Cell" (AT&T) or "Network Extender" (Verizon), which sounds a lot like a booster. You can even use it similarly: put it in your house and the femtocell will broadcast a powerful cellular signal.

The difference is that the femtocell base station needs to be plugged into your router to use your internet connection. This is how it connects your phone to the carrier's server. This enables femtocells to work in areas where you have no signal at all. So it is suitable for apartments in rural areas or surrounded by high-rise buildings.

The downside is that if you get one of them from a carrier, it only works on that carrier’s phone. Furthermore, in this case, third-party options covering multiple operators actually do not exist. It also does not work well with satellite Internet.

The strangest side effect of femtocell is that almost anyone can use it, as long as they subscribe to the same carrier, even people passing by your house. Their calls will go through your Internet connection, which may slow down your Wi-Fi traffic and affect a lot of activities, such as streaming videos or large downloads. With Verizon, you can set a priority number so that you always get service first. Despite this, other people may still steal your Internet connection.

Many times, your mobile provider will borrow femtocell base stations from you for free or one-time. It is better for operators to provide a femto base station for free instead of losing a customer.

If your carrier does not lend you for free, femtocell will cost you between $50 and $250, depending on the brand and the amount of data.

A Wi-Fi wireless network may already be set up in your home. If you use it for home Internet access on smartphones and tablets, you can already save on cellular data plans and avoid overuse.

Wi-Fi can also use Skype, Google Hangouts, Apple's iMessage and other third-party messaging applications (such as WhatsApp) to make calls and send text messages. So if you don’t have a signal, don’t worry. Historically, this meant that both parties (caller and receiver) used the same application.

However, now, all four major operators T-Mobile, AT&T, Sprint and Verizon have developed Wi-Fi calling capabilities for their phones. When this feature is enabled due to a weak signal, your phone will automatically switch to an open Wi-Fi network nearby, so you won’t even notice.

You can also switch to a phone system like Republic Wireless, which uses Wi-Fi calling as its main function. Republic Wireless offers a low-cost plan because it mainly relies on Wi-Fi for calls and texting, and uses cellular networks only when Wi-Fi is not available. Likewise, the switching is seamless.

Of course, calling via Wi-Fi means you need a Wi-Fi network. Tap or click here to always find the nearest free Wi-Fi. simple!
