The Internet sees the phone, but now I can’t access any of the sites (Viber, Google, YouTube...), nor with one of the SIM cards, it says that there is no access. What should I do? I have money on two SIM cards, internet on two SIM cards connected, but applications do not see the connection?

Samsung Galaxy 3 Duos, the Internet is turned on on the second SIM card, but if the connection is lost on the second SIM card, then the phone automatically switches the Internet to the first SIM card, what nonsense! !??

Samsung got smart as usual, in Lenovo it switches to top menu One click on the icon for mobile data, but in Samsung this icon only turns off or turns on the transmission, it’s very inconvenient. Samsung gets 2 points for such torment.

the article helped me a lot Samsung smartphone Galaxy Grand Neo GT-I9060 Duos White could not change mobile data from one SIM card to another for a long time

Many modern smartphones support 2 SIM cards. After you have inserted SIM cards into your phone for the first time, I advise you to configure each SIM card through the SIM card manager. This is necessary for proper operation and to avoid confusion - which SIM card to use to call and access the Internet.

Settings, priority SIM card

To work we go to Settings – Connections – SIM card manager.

Before us 2 active SIM cards. You need to choose a priority SIM card for calls, SMS and Internet. Usually the default is always sim No. 1 (in my example this is Megafon). To change the settings, select “Calls”, “SMS”, “Mobile data” and select the desired SIM card.

SIM card settings

Each SIM card has its own settings available in the manager: Enabled/disabled, icon for identification (SMS, Internet, work, home, sim 1, sim 2), name and network mode. I don't recommend changing the settings if you don't understand them.

Optimal settings:

Call settings

Above we have selected a priority SIM card for calls. In the “Call Settings” menu we are asked: should we offer the choice of a SIM card each time to make an outgoing call, if a priority SIM card is not used? This option is useful for those who are forgetful when you constantly confuse the SIM card you are calling with. Personally, I don’t use this function and consider it unnecessary.

Active mode

When you enable the active mode here (in the SIM card manager settings), you can receive calls on both SIM cards even during a conversation. The feature is useful and enabled by default.

Mobile networks

Setting up a mobile network for each SIM card is easy. Settings – Connections – Mobile networks(the option is not available without a SIM card inserted).

Some phones support the installation of multiple SIM cards, each of which can be assigned specific actions. For example, you can use one SIM card only for calls and SMS, and another for mobile Internet.

Important! Before installing or removing a SIM card, turn off your device.

How to install SIM cards

How to see which SIM cards are installed

1. Open your phone settings.
2. Click SIM cards.
3. You can view information about the telecom operator and phone number for each installed SIM card. If there is no SIM card in the slot, you will see the corresponding message.

How to check SIM card status

How to assign actions to SIM cards

1. Open your phone settings.
2. Click SIM cards.
3. In the "Using SIM cards" section, assign actions for each card.
   • Mobile Internet. Please note that to transfer data via mobile network You can only select one SIM card.
   • Phone calls. Specify the SIM card for calls. Otherwise, you will need to make a choice before each call.
   • SMS. Select a SIM card for SMS exchange.

Unsophisticated experience of communicating with modern technology You can’t force a person into the settings section of your smartphone. This approach sometimes leads to confusion, and a gadget that has not been told exactly how to behave begins to live its own life. One striking example is a smartphone with two SIM cards, which people use together to optimize spending on mobile communications. However, there will be zero sense in such optimization if the smartphone does not receive from you precise instructions, when and which SIM card should be used.

It’s easier with calls and SMS: most smartphones, when you try to call or send a message, ask each time which SIM card number you need to use. The main thing here is to initially know your SIM cards in person and understand which one is the first and which is the second. As a last resort, this point can be clarified in the settings, in the “SIM Card Management” section.

There you can see which operator serves each card.

If the operator is the same, as in our example, you will have to deal with the numbers. Each operator has its own options for clarifying the number corresponding to the SIM card. In MTS you can call from the desired SIM card to short number 0887: the number will be dictated by the answering machine. This call is free.

Let's go online

On your smartphone with two SIM cards, the situation with mobile Internet is more complicated. If you open the application for social network or the browser, your gadget, without asking you anything, simply connects to the Internet using the specified settings, and perhaps through the wrong SIM card. This is why it is important to be able to change settings.

In the screenshot above, find the “Default data transfer” option. You see that the data transfer (i.e. mobile internet) is configured for the second SIM card. At the very top of the screenshot you can see that for each of the SIM cards the following types are described: cellular networks, which can be used. In particular, the first SIM card has access to any network, including the fastest, 4G. The second card is only “capable” of 2G, and therefore is only suitable for calls and extremely slow mobile Internet. Obviously, you should change the settings by switching the Internet to the first SIM card, like this:

We climb under the hood

There is an important nuance: the availability of modern cellular networks often depends not on the SIM card and the complete coverage of operator networks, but on how you place the SIM cards in your gadget. The fact is that in many phone models, only one of the two SIM card slots can provide connection to 3G and 4G networks. The second slot has limited functionality and is “friendly” exclusively with 2G and calls. We took our screenshots from just such a smartphone.

If you mix up the slots and the SIM card for the mobile Internet is in the wrong place, you will have to swap the cards. In some smartphone models, during this procedure you will encounter another problem: sometimes the slots are designed for SIM cards different sizes. To resolve this problem, the SIM card can be replaced while maintaining the number at the operator’s office, telling its employee what size card you need. As a rule, the SIM card replacement procedure will not cost you anything.
