Most smartphone owners are accustomed to being able to talk on the phone and use the mobile Internet at the same time. But mobile Internet actually appeared on phones not so long ago. In just a few years, it has come a long way, developing, becoming more complex and expanding its capabilities.
First of all, this affected the development of mobile Internet networks. First, not very fast 2G appeared, then it was replaced by 3G coverage, today most city residents are accustomed to the latest version of 4G. The next generation of 5G networks is on the way, and the 6G standard is being tested in China.
Despite the acceleration of data exchange, there is one “small” problem. Each of these networks operates in its own frequency range, with different territorial coverage. And if there are several options, the phone has to independently determine which one to connect to.
And here a contradiction arises: the 2G network is the most widespread, it has the most stable signal. But the transfer of information is too slow (pages take a long time to load, especially pictures and videos). The 4G network is much faster, but has a smaller coverage area and a weaker signal. If you allow your smartphone to automatically select a network, it will choose 2G, although even with a weak signal, working with the 3rd or 4th generation standard will be more productive.
Let’s consider in which cases it is more profitable to make a choice, and when to give the “right of determination” to the smartphone’s automation.
Is CDMA better than GSM?
GSM users may have better voice quality than CDMA
users or vice versa in certain areas. … On the other hand, not all CDMA phones can transmit voice and data simultaneously. In addition to network congestion, CDMA call quality is generally better than GSM.

Which network mode should I choose?
In the smartphone settings menu, the user is offered items with which to configure the network. In them you can select connection types such as “3G only” or combinations: “Automatic 2G/3G/4G”. The number of lines in the menu may vary depending on the model and year of manufacture. In different situations, one of the points is most useful, so manufacturers offer the user to choose the preferred mode.
But to make an informed choice, you need to understand what different modes offer, what the disadvantages and advantages of each solution are. And why automatic detection of network type is not always the best option.
The difference between generations of cellular communications lies not only in protocols, frequency range, types of signal encryption and information transmission speed. They interact with voice calls differently.
If it was only necessary to get better communication quality (high Internet speed), the old networks would have been turned off long ago. But their advantage is that with fewer towers they provide a significant coverage area. And if you turn off the old type of network, many subscribers in rural areas will be left without communication. Old networks also have other features that should be taken into account when setting up.
Setting up profiles on Samsung phones
Creating multiple profiles on a device is useful if more than one person uses the features. Adding new profiles is available on Android operating systems from version 4.4 and higher. Tablets also support this functionality, but in limited quantities.
To add a new profile, you need to do the following:
- Pull down the notification panel and press the gear button.
- Scroll down the screen and find the item dedicated to users. After this step there are no significant differences between the models.
- Click on the “Add User” button to increase the number of available accounts.
- A window will appear where you should confirm the previously made decision. This completes the setup.
Note! You can set up a new profile immediately or later. In newer elements, text messages and calls are often disabled initially. To enable them, you need to go to the administrator account. Next to the new user’s name, you need to click on the gear icon, and then select “Enable calls and SMS.”
Switching between profiles, if necessary, is done through the standard control panel. Deleting information is also not difficult.
How to change operating mode
You can select a different network on Android phones in the settings window. Open the “Settings” tab, select additional (“More” item), go to the “Mobile networks” section, activate the “Network type” line and select the preferred one.
In older phones there are only two selection options - the 2G and 3G buttons. If you select 3G, the device works in both 2G and 3G modes. Newer versions have “3G only” or “4G only” options so that the device does not waste energy scanning bands and searching for other networks.
Android 9 devices
To work on a smartphone with Android 9 OS installed, you need:
- Open the “Settings” mode.
- Select the “Connections” tab.
- Go to "Mobile networks".
- Enter "Mode".
- Select the required type of coverage.
- Start using it.
If one of the modes is not displayed on the screen, it means that the smartphone (or tablet) does not have this feature. It will not be possible to influence the tablet programmatically; its functionality can be expanded at the hardware level.
Devices with Android 8, 7, 6, 5
If the phone runs on one of the earlier versions of Android (5-8), setup is carried out as follows:
- Open menu.
- Select "Settings".
- Go to “Connections” (if such an item is in the menu. In some versions, the next step goes immediately).
- Select "Mobile networks". (Similar names are “More”, “Advanced settings”, “Other networks”, etc.).
- Switch to “Network Mode”.
- Select the option you prefer to work with. Instead of the usual designations, others may be used (2G = GSM, 3G = WCDMA, 4G = LTE).
As in the case of Android 9, it is impossible to add any mode to the list; they are “built into” the device at the production stage.
What is WCMDA?
When talking about WCDMA or GSM and what is the difference between them, it is always appropriate to mention that WCMDA is to some extent an add-on that improves the GSM standard. Or rather, this is how everything was originally intended, but today WCDMA is a third-generation communication standard, which is based on seven international projects. But GSM remained the second generation communication standard (read 2G).
WCDMA is based on DS-CDMA technology, which, compared to TDMA, is more resistant to interference and has higher throughput. Phones that operate in the WCMDA environment can perform the same functions as in the GSM standard (transfer of voice or digital information), but the quality and speed will be much higher. Therefore, operators supporting WCMDA provide Internet access services at higher speeds.
In what cases do you change the network mode?
Most often, you need to force a change in operating mode:
- when traveling from the city to an area where there is only 2G coverage, so that the phone does not waste battery life scanning other frequencies;
- if the smartphone is connected via a new connection with a weak signal, but you need a high connection speed;
- if the higher-generation network is too congested, and the “old” one is almost free of users (which gives a performance gain);
- if the user does not care about high data transfer speeds, and a fee is charged for data exchange in more modern networks;
- if the user does not need the Internet.
Mobile Internet on Samsung phones
On any phone you can adjust settings regarding:
- passwords;
- usernames;
- access point APN and its characteristics;
- data channel;
- the name assigned to the profile. Without it, the mobile phone simply will not get in touch.
Note! The parameters must match the mobile operator and the phone itself.
Usually the Internet starts working immediately after a SIM card is inserted into the device. All parameters are set automatically. Therefore, practically no additional actions are required on the part of the user. He will instantly understand how to connect the Internet on a Samsung phone.
Automatic Internet setup (recommended method)
If the Internet does not start working after the initial installation of the SIM card, it is recommended to proceed to the following steps:
- Send a request to the operator asking to send the settings. A message will come from him in the form of an envelope with a gear. This is the usual icon used to indicate such messages.
- Open the sent text.
- Select the item called “Application: Internet”.
- Click on the “Install” button.
- If you need to enter a PIN code, use the numbers 1234 or 0000. If such combinations do not work, it is better to call technical support and clarify the information of interest.
- Confirm with the “Yes” button.
- Enable the "Mobile data" item.
- Reboot your device.

Note! After this, the connection should work without problems. The instructions on how to set up the Internet on a Samsung Galaxy A5 will be approximately the same.
A smartphone purchased in another country does not work with my SIM card
In different countries, operators use different frequencies for the same network generations. Before buying a device, check that the frequencies on which the connection operates are the same. If the frequencies are different, the connection will not work.
It’s hard to imagine life without a smartphone, and mobile devices themselves without a stable, working Internet. Setting it up correctly on Samsung gadgets should not present any particular difficulties. The main thing is to follow a few simple tips to figure out how to turn on the Internet on Samsung.
4G only
Even if you live in central areas of the city, where 4G coverage fully meets the needs of all users, switching to 4G only mode is not always the smartest decision. First you need to clarify which version of fourth generation communications works in your area using VoLTE technology.
Before the advent of this technology, the network did not provide voice calls, but was used only for transmitting Internet data. As a result, when working in the first versions of the 4G network, the phone switched to 2G/3G mode for conversation, and when it ended, it returned to 4G. Which required the use of additional battery life.
Only with the advent of VoLTE were smartphones able to transmit calls and data within the same network, without switching, searching for other base stations, and “jumping” between standards. You need to enable this mode only if the “VoLTE” symbol is displayed in the top information line. Otherwise, you risk missing an important call and not getting in touch if necessary.

The stability and quality of mobile communications depends on the coverage area provided by the operator’s base stations and the load on them. Accordingly, there are several reasons for the deterioration of communication quality. You can notice this by such signs as: it is impossible to make a call, nothing is clear during a conversation, the data transfer speed leaves much to be desired - the Internet does not load. This may be due to overload of the base station due to the connection of a large number of subscribers. But more often the reason for poor communication lies in the problems and physics of the process of passing radio waves. Communication may deteriorate due to dense buildings, terrain, long distance to the base station .
Base station overloads are quite rare. You can encounter it at public events or at those moments when everyone suddenly needs to make a phone call urgently. For example, on New Year's Day, as soon as the chimes struck. And this problem can be solved relatively simply - after a short interval of time everything will work.
But the problem is that your country house is located in a “dead zone” or a remote village, to which the signal from the nearest tower can barely reach - this is a really difficult problem that will not resolve in a few minutes and will not be solved at all without additional equipment. Also, similar difficulties arise, for example, in cases where your office/shop is located in a semi-basement/basement or inside a large reinforced concrete building. In this case, the problem with cellular communication must be solved by installing additional equipment or changing the settings of the smartphone. We will now figure out what and how to do in this case.
Auto 2G/3G/4G
In the factory settings of each phone, this mode is set, with automatic selection of the best and most “advanced” network. They suggest choosing the same mode if you decide to set up a network in a company office.
In this case, the smartphone independently determines which networks are available in the region and which one to connect to for calls and data transfer. At the same time, it automatically evaluates the signal level, reception quality, priorities, and other network settings. The owner does not need to monitor whether he has left the network coverage area.
