Welcome to droidium.ru! Quite often, one unpleasant thing happens with tablet computers and mobile phones. On a seemingly working device, the network or the Internet suddenly disappears, while the phone or tablet loses connection. Why does the network on the Samsung Galaxy S5 SM-G900H disappear? We dare to assure the problems with the Internet and the network can arise from the device of any manufacturer. If for no reason, your Samsung Galaxy S5 SM-G900H phone has lost Internet connection and mobile network, then our publication will probably help to understand the cause of the problem.
It’s no secret that on modern phones there can be three types of communication: 2G digital cellular communication, 3G broadband digital cellular communication and the ability to connect the phone via Wi-Fi. Tablets are also not far behind, and in most models there is a way to connect to the Internet via Wi-Fi, and many manufacturers offer tablet computers with the ability to connect to a 3G network of a mobile operator.
Samsung Galaxy S5 SM-G900H loses 3G network and mobile Internet connection
If your smartphone loses its 3G network, then there may be several reasons for the problem. The first reason that the 3G Internet disappears is an insufficient signal. The phone may not be in the best place to receive a signal, as a result of which there will be poor reception on 2G / 3G. If you are outside the city, or among tall concrete structures (such as skyscrapers), this may affect reception. In principle, this problem can be observed in any operator, with the exception of Beeline, Megafon, MTS, MTS, Skylink, Rostelekom, Kyivstar, Kyiv, Djuice and others.
On the website of each mobile operator that provides access to a 3G network there is a network coverage map. Unfortunately, such cards are very relative and may not coincide with reality. But still, we recommend that you familiarize yourself with the coverage map of your mobile operator. Perhaps the reason for the loss of communication is precisely in the insufficient signal. Sometimes the problem when a tablet or phone loses connection in a normal 2G network may be due to the 3G network turned on, which is unstable. This is due to the fact that the device with a bad 3G network switches to a regular 2G cellular network, which takes some time. At this time interval, communication breaks can occur.

If you do not need a 3G network at a particular point in time, then it makes sense to disable 3G in the settings. In addition to the bad signal and the loss of its source, there are a couple of probable reasons why the Samsung Galaxy S5 SM-G900H phone loses 3G Internet. The problem may be with the old sim card. Over time, everything wears out. Of course, this is not the case when the device does not see the SIM card at all. But the problem with the card should not be debited. The worst option is when the Internet disappears due to a hardware malfunction of the GSM module or receiving antenna. If the Samsung Galaxy S5 SM-G900H very poorly catches or does not catch the network at all, then the hardware problem is very likely. You can eliminate the malfunction of the SIM card by checking the card on another device. But only a specialist can check the GSM module or the problem antenna. Sometimes in such cases, wiping the contacts of the antenna loops and the module helps.
Wifi internet disappears on Samsung Galaxy S5 SM-G900H
If on the Samsung Galaxy S5 SM-G900H smartphone connected to Wi-Fi periodically the Internet disappears, then there may be three reasons. The first reason is poor quality provider services. Even such renowned providers as Beeline, Rostelekom, NetByNet, 2Com, Qwerty, MGTS, ByFly may have problems providing the Internet access service. But in this case, this is not about that. The fact is that some providers provide one Internet channel for all users at home or in the doorway and during peak hours, mainly in the evening, communication with the network can be very poor. If you notice signs of speed failure when downloading files and torrents, or when surfing through a browser, then it may be worth measuring the incoming and outgoing speeds of the Internet connection.
The second reason. Quite often, WiFi disappears due to a weak signal. The problem can be like in a router or access point. The power of the distributing antenna of the router may not be enough for the whole room. Or the signal is obstructed by the walls. Therefore, if the Samsung Galaxy S5 SM-G900H loses WiFi signal, then it is worth checking the operation of the gadget near the source. Sometimes a flashing or installing a reinforced antenna helps to solve the problem with the router, and sometimes just turning the router off / on can be enough. Here we do not consider the case when the gadget does not connect to the wi-fi network at all. This problem is described in detail in the article at the specified link.
The third reason for losing Wi-Fi signal can be hidden in the Wi-Fi module of the phone. For example, when the Internet disappears, and after a reboot appears, the reason may be a physical malfunction of the Samsung Galaxy S5 SM-G900H. If you are convinced that the WiFi router has nothing to do with it, and the smartphone still loses Wi-Fi, then a wifi module breakdown is quite likely. Here you can not do without checking the module. In addition to the described problems with the loss of WiFi and 3G Internet, installed applications can adversely affect communication. If up to a certain point everything worked for you, remember that you recently installed on the Samsung Galaxy S5 SM-G900H, there may be a problem in a recently installed program or game.
