More and more mobile telephony infrastructures are better, especially in urban areas and on main roads. But still sometimes we have connection problems. In Spain there are four operators They have their own network: Movistar, Vodafone, Orange and Yoigo. Then there are agreements between these and the rest of companies to share their networks.
Currently there are three types of signals that we use with our mobile devices connected with a sim card: 2G for voice calls and text messages (sms), and 3G or 4G for data. The normal thing is that smartphones are configured at the factory to connect automatically to the best signal detected, between 3G and 4G. And if we disable the data connection, it will only connect to the 2G network.
There are several applications to detect the level of signal, but among all we highlight OpenSignal
There can be several situations where sometimes the signal we receive from our mobile phone company is not coming to us correctly. But the first thing we must detect is where this happens. We have two usual scenarios: abroad (within a population or outside of it) or at home.
There are several applications to detect the level of signal, but among all we highlight OpenSignal (Android or iOS). It is a simple application to manage and free. We are going to give some solutions depending on where we have the problem with the coverage.
Coverage problems abroad
If we have a signal too weak, we detect some slow problem with the data connection (discarding if we have exceeded the limit of our tariff), some cuts appear in a telephone conversation or another problem arises related to the connection, it is clear that we must see the level of signal at that time in the area.
We can see the quality level of the signal with the OpenSignal application. This offers us a pretty detailed information. It indicates the location of the antenna to which our device connects. In addition, depending on the color of the graph (green for good coverage and red for bad coverage) it shows the intensity level of the signal reflected in the map of the application.
The use of two sim cards from different operators, can solve some mobile coverage problems
What solutions can we have to improve the connection abroad? Well, if it is something punctual in an area, we could manually change the configuration in the mobile. This is done in many Android phones in the terminal menu: Connections - Mobile network. There we can establish that only connect in 2G mode (an exceptional case only for calls), 3G or 4G (for voice and data). This helps when there are many fluctuations in the automatic change of networks (we see how the icon of H +, 4G, etc. changes a lot).
If we move a lot and we need to have a stability and make sure that we always have an optimal connection. The best solution is to check which companies offer good coverage where we travel, and have two sim cards from different operators. If our means of transport is a car or a truck, and we need to be always connected, they exist in the market mobile signal amplifiers for vehicles. These are usually easy to install, although there is always the possibility of a technical service.
Home coverage problems
The first thing is to see the point where the coverage is lower or begins to decrease. We can detect this with the signal level on our smartphone or tablet (the number of 'lines' of coverage), or with the OpenSignal application (this gives us greater precision).
There may be several reasons why we have some kind of signal loss inside the house: either by possible interferences that are being caused by some elements (furniture with metal parts, appliances, or part of the structure of the house).
There are mobile signal amplifiers for both home and vehicles
Due to the difficulty of modifying any of these elements, or because of the nature of the place, it will depend on the need we have to ensure good coverage in an area of the house. If it is something specific, we could establish the network connection in manual mode (as explained above). Also, if we have covered the WiFi signal in that area, the problem of Internet connection would be solved.
But if it is very important that we have that area covered with a good signal (for example if we have a surveillance device or a medical device to report vital signs data) the best option is to install a signal amplifier. These improve the signal of all the companies that operate in the area. And the price varies depending on the type of signal it amplifies (only 2G and 3G are cheaper than those that also amplify the 4G signal).
Finally, if we are thinking of changing mobile companies, we recommend taking a look at the signal level with an application such as OpenSignal. This way we can be sure that with the change we have enough coverage.
