How to properly configure a phone with two SIM cards to access the Internet?

Mobile Internet provided by a mobile operator can be “unlimited”. But this tariff plan requires increased financial investment.

For a number of reasons, many smartphone owners have several SIM cards from different mobile operators. But one phone can have SIM cards and one operator installed in order to have several phone numbers. As a rule, tariff plans of cellular operators also provide mobile Internet in the package of services, but at the same time stipulate a strict limit on the amount of data transmitted over their mobile communications.

Knowing how to switch SIM cards to Honor, you can set priority in receiving/making calls, as well as using the Internet, at any time. In the comments, tell us how you solve the issue of making changes to SIM settings, and what difficulties arose when solving the problem.

Why set up SIM cards?

This needs to be done in order to receive calls only on one or two SIM cards at the same time, and also 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 can be applied to it. Namely, the configuration 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 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 one of them is empty, or rather, it is not in the phone.

What to do if your smartphone does not see one or both SIM cards?

There are several reasons why a SIM card may not work. This may be related to the technical and software parts. Installing unofficial firmware is one of the main causes of failures in mobile communications. Installed elements may have been incorrectly rewritten or may not work with the selected phone model. To solve this you need to find a suitable version of the operating system.

Another reason is due to a broken SIM card tray. Most often, problems with connectors occur after a fall or mechanical failure. For example, after water or dust gets into the case. If the part is damaged, the smartphone will not accept any of the cards. A complete replacement of the part will be required. In rare cases, the problem can be resolved by cleaning the holder.

The last option that could cause a failure is a problem with the card itself. To check its functionality, we recommend inserting it into another phone. If the connection does not appear on another device, this automatically excludes a problem with the system and parts of the smartphone. The card is replaced at the nearest operator's salon, after providing information about recent calls and passport data.

The latest models of smartphones, as a rule, have the ability to work with several cellular operators simultaneously.

To do this, the developers have included in the design of the phone the ability to install at least two SIM cards at the same time, plus an additional memory card to increase the amount of information stored on the phone.

Mobile operators, in addition to their cellular services, provide the ability to access the Internet via mobile data transmission at speeds comparable to the capabilities of Internet providers transmitting information via wire.

Using the button located on the side of the phone.

The screen shows the one that is active, that is, from which calls will originate.

Try switching SIM cards by pressing a button while dialing a number.

Smartphones with multiple SIM cards have become commonplace. But the principles of operation of the technology and the method of editing parameters are not made intuitively. In this article we will tell you how to set up
2 SIM cards on an Android
smartphone.

Disabling by operator

If you are sure that you no longer need the Internet function, you can completely disable it using your operator’s contact center. Contact him by phone and leave a request to disconnect. To resolve the issue, you may need to go to the office to fill out an application. After all issues are resolved, the operator’s technical support will disable the data service, and you will only have to reboot your device for the changes to take effect. Certain mobile applications use the Internet connection quite actively. This feature can cause serious harm to people who do not subscribe to unlimited Internet tariffs.

How to switch SIM cards

Before switching SIM cards on Honor, understand the principles of operation of the smartphone. In most cases, the mobile device manufacturer provides the ability to work on two SIM cards at once. This means that after you insert the SIM card, calls will be made to any of the numbers depending on where the call is received. As for dialing, it is done from the default SIM card. The same applies to the mobile Internet function. But these settings can be changed to suit personal preferences.

First, let's look at how to switch a SIM card to Honor on Android 10 version in the Honor 20 phone. Note that such instructions will also be relevant for other brand models with an updated operating system.

Take the following steps to set up a SIM card:

Enter "Settings".

Find the “Mobile network” item and go to it.

Find the item “Manage SIM cards” and click on it.

Here it’s easy to switch the SIM card to Honor based on your preferences. To do this, move the toggle switch to the right or left side. In the second case, the SIM is completely disabled.

A little lower you can set the default card for the Internet. Only one of the options is available to choose from here. Next there is the item “Default calls”. At this stage it is easy to switch calls to SIM1 or SIM2. If you set “Not specified”, each time you dial a number you will have to choose which card the call is made from.

For convenience, you can set up calls and enable call forwarding in the next section for the first and second SIM.

In older models, it is easy to switch cards to Honor using a different scheme. Take the following steps:

Open Settings.
Go to the "Wireless Networks" section.

Find the “SIM Card Settings” section.

Make the necessary changes taking into account the principles discussed above.

Here you can also switch SIM cards for calls and the Internet, and set forwarding if necessary.

A special approach applies when using the Internet. If the amount of traffic on one SIM card runs out, you don’t need to switch anything. The phone automatically disconnects the SIM where the traffic has ended and offers to switch to a second SIM. To do this, a corresponding notification appears on the smartphone screen. After clicking the corresponding button, the system takes you to the settings section, where you need to make a number of changes.

basic settings

These settings affect all working SIM cards, and not each one separately:

Mobile Internet: on/off. Allows data transfer through the operator's mobile network.
Dual 4G mode. At the same time, both SIM cards can work in 4G mode (fast Internet + calls). But this quickly drains the phone battery.
Mobile Internet during VoLTE calls (voice call transmission over high-speed LTE, or 4G networks). Those. During such a call, the Internet will work on the second SIM card. The option is supported by the Big Three operators in Russia: Megafon, MTS, Beeline.
Data transfer - traffic limitation for each SIM card.
Internet in roaming - to use or not. Be aware of super-expensive internet plans in other countries.
Always receive MMS—receive these messages even when the Internet is turned off.
Default calls. Select which SIM card (preferred) you will make calls from.
Internet by default. Choose which SIM card you will use the Internet on.

Data transfer

Here we can configure Internet use for each SIM card separately, depending on your tariff plan. Go to Settings > SIM cards and mobile networks > Data.

Enable “Traffic Control” and go to the “Tariff Plan” settings:

Traffic limit - set a monthly traffic limit. For example, for me it is 2GB/month.
If exceeded, notify and turn off the Internet or simply notify.
The warning threshold - when I see a warning - is 80%, i.e. after 1.6GB of used traffic package.
Accounting start date - what day of the month to start calculations. Usually the tariff is valid from the first day of each month.

And for additional settings, use the following options:

Widget in the notification shade—show the widget or not.
Show network speed - current Internet connection speed.
Send traffic reports. I advise you to disable sending reports to Xiaomi.
Disclaimer - a license agreement that the company and the mobile operator do not owe you anything, all risks are solely on the user.

Setting up a phone with 2 SIM cards for Internet access

There is no need to configure a SIM card yourself to access the Internet. Cellular operators send automatic settings to your phone immediately after connecting to a tariff plan. Users who use two cards in a device often purchase different plans.

On one SIM card they install a plan with unlimited Internet, and on the second they usually install a simple TP for calls, where a certain amount of money is withdrawn for each megabyte spent. But, some users purchase two tariffs with a specific traffic package at once. Then, when the limit on one number is exhausted, you will need to switch to another.
