What to do if the smartphone does not take
The causes for a smartphone that doesn't take can be multiple. Here are some solutions to try to remedy a scarce or totally absent signal
Calls, text messages, online browsing, updating of social media, exchange of e-mail messages, listening to music and watching videos, checking the traffic situation and receiving suggestions on the way forward. These are just some of the operations we can perform - and we do every day - with our smartphone. Having become a multi-purpose center, the smartphone has seen its exponentially growing computing power and battery life: it is no wonder, therefore, that these two are the most sought after technical characteristics by those who have to buy a new mobile phone.
What few people do notice, however, is the power and goodness of cellular signal reception. Even if the smartphone you buy will have the most powerful SoC or is able to guarantee hours and hours of autonomy, without connection to the cell line - and, consequently, without Internet - you can do very little. So what do you do if your smartphone doesn't take? Do we throw it and take another one or do we try to solve the problem with more or less homemade tricks?
Looking for the lost signal
The most adequate answer, especially if it is a fairly recent model, is obviously the second. Even if the smartphone does not take well, in fact, there are some tricks that allow you to improve the reception of the device and allow us, as a result, to make the most of its functionality and potential. In most cases it is a matter of advice dictated by common sense: it will not be difficult to implement them, but you will still have to be careful in order to risk complicating the situation further.
Switch off and on again
If your smartphone worked perfectly until a few moments ago and suddenly stopped receiving the signal, it is likely to be a small bug or a temporary glitch in the operating system. To solve it, try to activate the airplane mode, wait about ten seconds and deactivate it: if it is a minor problem, everything should be solved with this simple operation. Should the problem persist, turn off the phone, wait 10 seconds in this case too and turn it back on. It may seem like a "good" solution, but very often it brings excellent results.
Check that there are no network problems
The lack of signal - or the inability to navigate and make phone calls - may not even depend on your device. It could also be that your operator's network is experiencing a malfunction or temporary failure, preventing you from being able to make the best use of your smartphone. To make sure it is an operator problem, you can follow two paths: check on Twitter if there are other users' reports (for example with a search by hashtag #xxxdown, where instead of xxx enter the name of your operator) o news launched by reliable newspapers; or rely on portals that make the reporting failure their "reason for living" (take, for example, downdetector.it, in which everyone can report a malfunction of any communication service, including cellular networks).
Reset network settings
If the services of your operator have no problems and the first trick to improve the reception of the smartphone has not given the desired results, try to reset the network settings of the phone. In this way you will delete all the old settings (including Wi-Fi preferences, passwords and saved Bluetooth networks) and, with them, any bugs or glitches that have arisen due to excessive use of the device. If you have an iPhone, simply open the Settings, click on General, Reset and Restore network settings
How to improve smartphone reception at home
In the event that reception problems occur especially when you are indoors (for example at home or in the office), there are some useful tricks to improve smartphone reception in just a few seconds. First of all, try to put the device near the windows, where the signal from the outside should reach more strongly. If you can't do it - your desk, for example, is in the middle of the building, with no direct outward facing - you can always buy an internal signal amplifier or repeater, which "intercepts" the cellular signal outside and he repeats it inside, allowing you to have signal even in the most difficult areas to reach (the same system, for example, is used inside the tunnels or the metro). As a last resort, you can play the Wi-Fi card: until you go back outside, use the wireless Internet, even to make calls, in case your smartphone allows it.
What to do if the smartphone never takes
Do you have problems receiving continuously and wherever you are? The possible causes can be three: the smartphone, the SIM or the operator. Let's start with the last of the listed causes: it could be, in fact, that the area in which you live or work does not have a very efficient coverage by the operator. Maybe you are at the edge of the area covered by one of the few cells in the area and your smartphone has difficulty connecting to the network. If, on the other hand, your neighbors do not have reception problems with the same operator, the malfunction could be caused by the SIM or the smartphone. If you have another smartphone or mobile phone, insert the SIM and test it: if it has the same problems, then it has reached the end of its "life cycle" and must be replaced. Otherwise, reception problems are caused by your smartphone, now to be replaced.
