Finding a device's identification number is one of those routine tasks that users encounter unexpectedly. Usually, the need Find out the Wi-Fi modem number This occurs when registering a SIM card, activating a data plan, or setting up roaming while traveling. Depending on the type of equipment, the "number" may refer to completely different data: it could be the SIM card's IMSI, the device's IMEI, or even a unique ID assigned by the operator within its internal network.
Modern USB modems Portable routers often lack a physical screen that can display this information with a simple press of a button. Unlike smartphones, where entering a USSD code is sufficient, a more in-depth approach is required. You may need to access the web interface, install specialized software, or even disassemble the case if the stickers have worn off. It's important to immediately determine which identifier is required for your specific task.
In this article, we'll take a detailed look at all possible data retrieval methods. We'll cover browser-based software, command line methods, working with SIM cards from different carriers, and physical search methods. Data entry accuracy Registration is critical, so don't skip this step. Follow the instructions carefully to avoid errors when connecting to the network.
Differences between IMEI, IMSI and ICCID
Before starting your search, it's important to clearly understand the difference between technical identifiers. Users often confuse these concepts, leading to errors when filling out forms in the operator's personal account. IMEI (International Mobile Equipment Identity) is a unique fifteen-digit number assigned to the equipment itself. It's hardcoded into the modem at the factory and doesn't change when the SIM card is replaced. This number is often required to unlock or track the device.
On the other side, ICCID (Integrated Circuit Card Identifier) ββis the serial number of the SIM card itself. It consists of 19 or 20 digits and is printed on the plastic base of the card. Telecom operators use this number to link a plan and activate services. The third important parameter is IMSI (International Mobile Subscriber Identity), which is stored in the SIM card's memory and used by the network to identify the subscriber. In most cases, when people ask "how to find a number," they're referring to the IMSI or ICCID.
Confusion arises because some modem interfaces display these data together. For example, the connection status may show both the device's IMEI and the inserted SIM card's IMSI. If you try to activate the plan by entering the IMEI instead of the SIM card number, the system will return an error. Therefore, always check with your operator or in the instructions to determine which code is required.
Using the modem's web interface
The most reliable and universal way to get complete information about a device is to log in to its web interface. Almost all modern USB modems And 4G routers (Huawei, ZTE, Alcatel, Keenetic) have a built-in control page. Accessing it doesn't always require an active internet connection, as the page is stored in the device's memory. Simply open any browser and enter the gateway's IP address in the address bar. Most often, this is 192.168.8.1 or 192.168.1.1, but the address may differ depending on the model.
After entering the address, the system will ask for a login and password. By default, they are often standard, for example, login admin and password adminHowever, it's best to look for this information on a sticker under the device's cover or in the documentation. Once in the menu, look for sections titled "Status," "About," "Device Information," or "System Information." This is where the IMEI, IMSI, and ICCID fields are typically located.
β οΈ Attention: Firmware interfaces are constantly updated. The menu layout may differ from that described. If you can't find the section you need, try switching the interface language to Englishβtechnical data is often only available in the English version of the menu.
In some cases, telecom operators block access to advanced settings on their branded modems. If the standard login doesn't provide full access, upgrading to a universal firmware may be necessary. However, this is a risky procedure that can void the warranty. For basic viewing of the SIM card number, the standard menu is usually sufficient.
Software methods: DC-Unlocker and terminal
If the web interface is unavailable or doesn't display the required data, specialized utilities come to the rescue. One of the most powerful programs for working with modems is DC-UnlockerThis is a professional tool that allows you to interact with your modem using AT commands. The program is paid, but it has a free trial period or limited functionality, which is often sufficient for viewing information. It supports hundreds of device models based on chipsets from Huawei, Qualcomm, Sierra Wireless, and others.
After connecting the modem to the computer and launching the program, click the "Search" button. The utility will determine the device model, firmware version, and IMEI. To find the SIM card number (ICCID/IMSI), go to the "Manual Selection" tab and enter the appropriate AT command. For most modems, the command to obtain the ICCID looks like this: AT+CCID, and for IMSI - AT+CIMIThe modem's response will appear in the lower window of the program.
AT+CCID?+CCID: 89701019000001234567
OK
An alternative is to use the Windows command line if the modem emulates a COM port. However, this requires knowledge of the exact port number and familiarity with hyperterminals. For the average user, the connection DC-Unlocker or similar software (for example, Mobile Partner) is the most convenient solution. These programs also allow you to update firmware and change network settings.
What should I do if the program says βNo modem foundβ?
This often happens if the modem is operating in "Modem Only" mode or the drivers are installed incorrectly. Try removing the SIM card before connecting the device or reinstalling the drivers in Device Manager by selecting "Manual Search."
Commands for obtaining the SIM card number
For those who prefer manual control or use Linux systems, knowledge of AT commands will be extremely useful. These commands are sent directly to the device and allow you to receive responses in text format. Below is a table of the basic commands that will help you Find out the Wi-Fi modem number and SIM cards. Please note that the syntax may vary slightly depending on the chipset manufacturer.
| Team | Description | Example answer |
|---|---|---|
AT+CGSN |
Requesting the device's IMEI | 863245030123456 |
AT+CCID |
Requesting the ICCID of a SIM card | 89701019000001234567 |
AT+CIMI |
Requesting a subscriber's IMSI | 250011234567890 |
AT+CSQ |
Checking the signal level | +CSQ: 23,99 |
These commands can be entered not only in DC-Unlocker, but also in Arduino, Putty, or specialized Android consoles (if OTG is available). It's important to send the command and wait for a response. OK or ERROR. If it comes ERRORPerhaps the SIM card isn't detected or doesn't have a PIN (if one is set). In this case, you'll first need to send the PIN entry command: AT+CPIN="1234".
Using the command line offers the advantage of speed and automation. You can create a script that will automatically read the modem's parameters and save them to a log file when it's connected. This is especially useful for system administrators managing a network of dozens of modems. However, for a one-time procedure, entering the command manually is sufficient.
Physical examination and documentation
Don't forget about the simplest, "analog" methods. Any certified device must have an information sticker on the body. USB modems It's often located under the removable cover where the SIM card slot is located. For portable routers, it's on the back or under the battery. If the sticker has worn off or peeled off, you can find the information in the original box.
The box usually has a printed barcode with a series of numbers. Look for the S/N (Serial Number), IMEI, or ICCID. Sometimes the SIM card number (ICCID) is located on the plastic card itself, from which you squeezed the SIM card. Keep this plastic backingβit serves as legal proof of ownership of the number and may be needed to restore access at a mobile phone store.
- π± Check the sticker under the battery or USB modem cover.
- π¦ Find the original packaging and user manual.
- πΎ Save the plastic base of the SIM card with the printed ICCID.
- π§Ύ Check your contract with your telecom operator or your purchase receipt.
If the device was purchased second-hand or on the used market, and there are no stickers or the box is lost, physical methods are out of the question. In this case, you'll only have to rely on software or contacting the previous owner. In rare cases, the number may be listed on the warranty card if the seller filled it out during the sale.
Operator specifics: MTS, Beeline, Megafon, Tele2
Different telecom operators may implement data access differently in their branded devices. For example, modems from MTS Often require you to log in to your personal account for activation, where the number is automatically added. If you need to find out the SIM card number, insert it into your phone and dial *100# Or check your phone's settings. However, if the modem is locked to a carrier, it may not recognize SIM cards from other companies.
U Beeline And Megaphone Devices supporting HiLink technology are popular, with a simplified web interface. In such cases, full technical data (IMEI, IMSI) may be hidden from the average user. Accessing them may require entering a hidden menu (for example, adding #debug to the address) or using third-party utilities. Tele2 often uses ZTE or Huawei devices, where standard methods work flawlessly.
β οΈ Attention: Tariff terms and registration rules are subject to change. Before attempting to activate or re-register your number, please check the current requirements on your operator's official website or in the app.
It's also worth keeping in mind that some carriers "bind" modems to their contracts when selling them. In this case, the device's number for the carrier will be not only the IMSI but also the internal contract ID. If you plan to use the modem with a SIM card from another carrier, make sure the device is unlocked. Otherwise, even if you know all the numbers, you won't be able to use the other network's services.

Frequently Asked Questions (FAQ)
Is it possible to find out the modem number without connecting to a computer?
Yes, if the device has a display (like some Huawei E5785 or MiFi models), the number can be found in the "About Device" or "Status" menu. The information is also always on a sticker under the battery or on the box. Without a display and a computer, finding the number is virtually impossible, as there is no interface for displaying the information.
What should I do if the modem detects the SIM card as "Unknown"?
This could mean the SIM card is damaged, the contacts are dirty, or the format (3G/4G) is incompatible. Try cleaning the SIM card contacts with an eraser. Also, check if the SIM card is locked with a PIN. If the problem persists across multiple devices, the card may be faulty and needs to be replaced by a carrier.
Is it safe to use modem unlocking software?
Using proven utilities (DC-Unlocker, Huawei Calculator) is generally safe, but there's always a risk of bricking the device if the flashing process is interrupted. Use such programs only if you're confident in the power supply and connection. Simply viewing the serial number poses virtually no risk.
Where can I find the IMEI number if the sticker on the modem is worn off?
If there's no sticker, the only way is software. Connect the modem to your PC, log in to the web interface (192.168.8.1), or use the AT command. AT+CGSN via the terminal. This data is taken from the device's internal memory and is independent of external stickers.
To sum it up, we can say that Find out the Wi-Fi modem number It's not difficult if you use the right approach. For most users, a quick look at the web interface or the case label is sufficient. Advanced users can use AT commands to obtain more in-depth technical information. The key is to clearly understand which identifier is required in your situation and proceed with caution.
