How to enable second SIM on Samsung

How to enable the second SIM card in the phone

The days when the telephone was an expensive luxury are long gone. Now, most of us have more than one telephone.

A classic example of such a situation is one phone for friends and family, another for work.

We just need to admit that carrying two phones is a little tiring (although it was not a burden before, but times are changing).

However, you can instead enable and use the second SIM (assuming the phone has a second slot, of course).

Simply put, it allows you to use two phone numbers with one mobile phone. this can be done on Samsung, Lenovo, Meizu and everyone else.

Phones with 2 built-in SIM card slots

Almost all latest mobile phones have dual SIM function as standard.

Under the hinged cover, you can see two slots in which SIM cards are placed, and we can safely use both.

At the moment, many devices allow you to use both numbers at the same time without switching from one to the other.

I will show here how to enable the second SIM card on Samsung Android 6.0.1, but first I recommend that you familiarize yourself with this entry. otherwise you may not be able to enable both.

It says that on many phones, only one of the cards can be active at any given time.

Then depending on the phone model you are using, you may need to switch between them

In this case, in old phones, you still need to reboot it if you want to enable the second SIM card. Newer ones allow you to select a map from the menu and activate it on the fly, without rebooting.

How to enable second SIM card slot on Samsung

To enable Samsung (in most others it is the same) to enable the 2 SIM card, go to settings and click “SIM Manager”.

Next, specify the numbers for sim1 and sim2 to which the call will be forwarded.

Only this should not always be done. Therefore, above I recommended that you familiarize yourself with devices that have 2 slots for SIM cards.

It all depends on the built-in radio modules. Perhaps your phone has two independent ones, then you can do without call forwarding.

How on Samsung Galaxy Ace 4 neo duos and other Samsung androids with two SIM cards enable Internet on the desired SIM card.

In this article, we will look at how to switch 3G, 4G to the correct SIM on a Samsung Galaxy with two SIM cards. Surely many users of Samsung Galaxy Duos smartphones faced a problem when they could not find in the settings how to switch the Internet to the desired SIM card. Since not all Android smartphones support high-speed 3G or 4G simultaneously on two SIM cards, and therefore in the phone settings there is an item where you can choose which SIM card to use for high-speed Internet. For this article, we took the Samsung Galaxy Ace 4 neo duos as an example, it supports two SIM cards from which we can choose on which SIM card to enable high-speed Internet. In the settings, we can select 2G or 3G networks or automatic mode where 2G and 3G modes are immediately activated, but the fact is that if you select 3G or automatic, then the other SIM card will work in the 2G network. As you probably already understood, there will be almost no Internet on a SIM card with 2G. Below we will show in detail with attached screenshots and describe how to activate 3G, 4G on the required SIM card on Samsung Galaxy. Sometimes it happens that both SIM cards work in the 2G network and therefore the user begins to think that the problems on the Internet are due to poor connection, and the fault of the low Internet speed may be that not one SIM card is activated to work with 3G or 4G networks. To solve this problem, you just need to enable dual mode on one of the SIM cards for high-speed Internet and good communication. Perhaps, on some phones, both SIM cards can support 3G and higher networks.

And so, in order to activate high-speed Internet on the desired sim card in Samsung Galaxy Ace 4 neo duos and similar Android devices, do the following.

We go into the settings and find the item Other networks. Below in the screenshot, I have highlighted the desired item. Perhaps, on some Samsung devices, this may be the item Wireless networks.

Next, in the menu that opens, select the item Mobile networks. We look at the screenshot attached below.

Now we see in which networks our SIM cards work in the phone. As you can see in the screenshot below, I have selected both SIM cards. The first SIM card works in automatic mode (2G and 3G), and the second SIM card only GSM (2G).

We select the desired SIM card for which we want to enable high-speed Internet 3G, 4G. It is better to choose automatic mode on the SIM card with which we use the Internet, then both the connection and the Internet will be good.

This is how we activated the Internet on the desired sim card in the Samsung Galaxy phone with support for two sim cards.

Switch between SIM

To switch between the active SIM cards in use, manufacturers add additional features to the software of their devices. At the same time, on some phones, a button for switching active cards is additionally implemented, located on the front side or side panel of the device. Some devices present the user with 2 keys for sending a call to the subscriber, each of which is assigned to each operator.

Principle of operation

The number of radio modules available for use in a mobile phone is determined by the manufacturer of the mobile device. In a dual SIM phone using 1 radio module, both SIM cards are in standby mode. When a call comes to the card of one operator, the second SIM card becomes unavailable. Thus, the phone allows you to use two SIMs, but there is still only one active card. A similar situation for phones with one radio module develops when using Internet services: only one SIM can receive and transmit packet data, while the second card is in standby mode.

Devices that have 2 built-in modules can simultaneously work with two telecom operators. During a telephone conversation, the subscriber can receive a call to the second SIM-card, i.e. if desired, the user has the ability to conduct conversations with two people without interrupting the call. As soon as the telephone user answers the second call, the first conversation is put on hold. After ending the conversation with the second caller, the user can return to the conversation with the first person.

Advantages and disadvantages

Among the advantages of such devices can be noted the ability to save on mobile communications. You can install cards from 2 different service providers in your phone. For example, the first operator can offer cheap calls to subscribers of telephone networks, and the second allows you to send cheap SMS or exchange packet data on the Internet. For people who use two phones in the course of their life, a dual-SIM device will become an ergonomic alternative.

Among the disadvantages of dual-SIM devices, one can note their overpriced cost compared to single-SIM models. Nevertheless, in the modern mobile phone market there are a large number of budget models that will satisfy the requirements of even the most economical consumer.

How to set up two SIM cards on an Android phone

The screenshot below shows that SIM 2 has been renamed and called Nadezhda. It is for her that the reception of calls and the Internet is configured, namely:

  • Voice call,
  • Video call,
  • Data network.

Such settings can be made in the SIM-card manager, in the “Preferred SIM-card” section:

If, for example, for the 2nd Simka you indicate that it will “catch” the Internet, then everything else will be configured automatically (Fig. 4-1). And there will be no inscription “No network” on the main page of the phone.

If you click on the inscription “Data network”. the window for choosing the preferred SIM-card will appear (Fig. 4-1).

In the same way as shown in fig. 4 and 4-1, you can select the preferred SIM for voice calls and video calls. At the same time, both SIM cards remain connected in hardware, as evidenced by two points in the SIM card manager:

  • SIM 1 and Hope are shown as active. If one of them is inactive, then its name will be written in a pale gray color.
  • The “Active mode” option is configured to “Receive calls on both SIM cards even during a call”.

If an Android phone with two sim cards

An Android phone with two SIM cards is usually purchased in order to insert two SIM cards there, possibly from different mobile operators, and as a result, instead of two phones, carry one with you. However, in fact, sometimes they still use one SIM card anyway.

For example, I gave up the idea of ​​using a second SIM card in a two-SIM phone. “The old fashioned way” and continue to use two telephones. Refused, in particular, due to problems that may arise when switching from a regular to a mini-SIM, which must be done for a dual-SIM phone. It turns out that it is advisable to first go to the bank to notify about the change in the size of the SIM-card (and, accordingly, about the change in its serial number), although the phone number remains the same. But without the code that comes in the SMS message to the phone, it will not be possible to confirm many actions on the Internet.

In addition, it is not always possible to remember what, that is, to the account of which important but rarely used service the phone is attached and, accordingly, where else a problem may arise when changing the SIM card format. True, the existence of such sensitivity on the size of the SIM card still depends on a particular bank and on specific services. Perhaps as technology advances, this problem will go away.

Why set up SIM cards

This must be done in order to receive calls only to one or simultaneously to two SIM cards, as well as to be able to access the Internet from the selected SIM card, as well as distribute Wi-Fi.

An Android phone is essentially a small computer, so many computer approaches are applicable to it. Namely, the setting of SIM cards occurs in hardware and software (hardware software).

For example, if you enable only one SIM card on your phone programmatically, that is, make it active, and leave the second SIM card inactive, but at the same time do not disable it in hardware, then you will eventually see a crossed-out circle icon on your phone. This icon means that the phone has two SIM cards, but at the same time one of them is empty, or rather, it is missing from the phone.

How do dual-SIM card phones work?
