Most phones get a dual identity by having two IMEI numbers. But what exactly is it? An IMEI is essentially a digital fingerprint. The device provider programs it. It is a code that consists of 15 digits and is always unique. Its name means an abbreviation of International Mobile Equipment Identity. The IMEI is obtained by every device that uses a SIM card, for example:

Cell phone;

Smartwatch;

Tablet;

Mobile broadband router;

IoT device.

With this number, each user's mobile device can be distinguished from billions of others. In this way, the mobile service provider always knows exactly which gadget is trying to connect to the network. This is especially important in cases where the phone is lost because the IMEI can be used to find the device. So, the answer to the question, “Why does my phone have two IMEI numbers?” is quite simple. However, the specifics of this system are a bit more complicated.

Dual IMEI is assigned to smartphones with two SIM cards since each receives its unique identifier number. The use of two SIM cards is especially useful for people who travel frequently or need to separate work and personal contacts. Moreover, the user can receive services from different providers, which ensures better communication. It also provides more privacy and, of course, freedom of action, which is essential for people who travel widely. Abroad, they can use a local card without spending money on roaming.

However, not all phones can support two IMEI numbers, even if they can use two SIM cards. That is why you should make sure your phone fully meets the requirements described above before purchasing it.

The IMEI is important to the user for several reasons.

Quality operation and security of the smartphone. This function makes life much more difficult for thieves because, with the help of IMEI, you can identify your phone or add it to a blacklist.

The ability to take advantage of dual identifiers for owners of smartphones that support two SIM cards, as each slot has its own IMEI.

Authentication and identification in the network because the provider receives this number every time the owner of the smartphone uses it.

Every smartphone receives an identification number from the manufacturer anyway. If a phone has two IMEI numbers, it becomes a significant advantage for its owner. This way, the device can easily connect to two different networks, which is especially useful in places with poor coverage.

So, if you can say, “I have two IMEI numbers,” this is an obvious benefit of your phone, especially since not all devices with two SIM cards have a dual identifier, which limits the smartphone's ability to connect to multiple networks simultaneously. Thus, when choosing a phone, it is important to check whether this feature is available. Before buying, make sure you have two IMEI numbers, for example, on your iPhone.

Usually, these offers are created for phones that support two SIM cards. So, if you want to get two different IMEI numbers, it is worth looking for a device with such capabilities. This gives you flexibility in choosing a network provider and significantly improves the quality of communication, which is important for active people.

So, you've identified, “My phone has two IMEI numbers.” What's next? What is the essence of this phenomenon, and what benefits can it bring? To begin with, you should understand that two IMEI numbers on a phone and two SIM cards are not the same. In the first case, it is a dual international identification number, and in the second case, the smartphone can support the operation of two cards. These technologies complement each other, improving network connectivity and protecting personal information.

Having two SIM cards does not mean you have two IMEI numbers on a phone. IMEI is an identifier associated with the device, namely, the card slot. A SIM can be used on different phones and has identifiers, such as MSISDN, IMSI, and ICCID.

IMSI (International Mobile Subscriber Identity) changes depending on the SIM card, but IMEI does not. It remains the same for each device. Today, with the advent of eSIM, it has become possible to use two cards on smartphones that have only one built-in slot. However, this does not mean the device will have two IMEI numbers.

If your phone shows two IMEI numbers, it opens up many possibilities. This feature allows you to manage your communication more efficiently because the user uses two SIM cards at the same time, which has the following advantages:

Improved connection. When there are two IMEI numbers, the user can quickly change the network. This makes it possible to stay in touch even in places remote from civilization, which is important for travelers.

More efficient organization of personal and business contacts on the phone.

Convenience because you can use two SIM cards, and there is no need to carry two phones.

Cost savings are associated with the choice of several mobile service providers. Moreover, when a phone has two IMEI numbers, you can choose the most favorable tariff plans. You can also, for example, use one card for data and another for phone calls.

Flexibility to adapt communication to the specific needs of the user.

Security. The IMEI number can be tracked down, even if the SIM card has been replaced.

It is quite easy to determine if there are two different IMEI numbers, for example, on iPhone. Enter the combination of numbers and signs *#06#. After that, your device's ID number will appear on the display. If the phone shows two IMEI numbers, you can easily get all the benefits of using two SIM cards.

There is an alternative way to check this information. However, remember that the settings may be slightly different on Android and iPhone. To check if there are two IMEI numbers, for example, on your iPhone 11, open the phone settings (the “About phone” or “About application” section). If two numbers appear, the IMEI is dual. This feature can only be used on phones that support two SIM cards. Therefore, if your device is one of them, it is likely to have two identifying numbers.

If you want to check the IMEI on the router, it is usually printed on a sticker on the device. Alternatively, you can check the ID number in the router settings using the software provided by the device manufacturer. You can also use the web interface to access the settings page. For this purpose, you need to enter the IP address of the router. As for finding the IMEI on the smartwatch, this information can be found in the device settings by going to the “General” menu section and then “About.” The names of the menu sections may vary depending on the manufacturer and software.
