Identify Sim Card Carrier

A telecommunications provider known as a SIM (Subscriber Identity Module) card carrier offers the necessary network infrastructure for a mobile device to operate. When a mobile device inserts a SIM card, it makes a link to the carrier’s network. It allows users to make calls, send texts, and access the internet on the gadget. In addition to choosing the type of service plan and degree of coverage that a person would receive, the carrier is in charge of providing the service. A reliable and cheap cell service depends on selecting the right carrier. It is because different carriers provide varying offerings, network coverage, and service plans. Let us learn how to identify a Sim card carrier.

Identify Sim Card Carrier


It is essential since the carrier decides what kind of services and coverage a client would get. The carrier provides the cellular network that enables calling, texting, and accessing data services. A person can choose the greatest solution for their needs with the help of the carrier. It is because different carriers have different network coverage, speeds, and available services. Knowing the carrier is crucial for device compatibility because some devices may be carrier-specific, meaning they are only compatible with specific carriers.

Methods to identify the carrier of a SIM card

  1. Identifying the carrier using the SIM card number: The ICCID (Integrated Circuit Card Identifier), often known as the SIM card number, can be used to identify the carrier. You can usually find the ICCID printed on the SIM card or by checking the device’s settings. The first four numbers of the ICCID often identify the carrier because they specify which company issued the SIM card.
  2. Using the mobile phone settings: To find out more about the device and the carrier, go to the “About” or “Settings” menu on the majority of handsets. This data may include the carrier name, network type, and other details about the network connection.
  3. Using a third-party app: The IMEI (International Mobile Equipment Identity) number of the handset can be used by several third-party tools to determine the carrier. These apps can offer details about the network type, carrier, and other characteristics of the device and network connection.

USSD code

Mobile networks employ USSD (Unstructured Supplementary Service Data) codes as a form of communication protocol when speaking with mobile devices. Short codes, usually beginning with * or #, are entered into the phone dialer and sent to the carrier’s network. The code is decoded by the carrier’s network, which then carries out the desired action, such as activating a particular service or verifying the balance of an account. USSD codes are frequently used for simple, quick tasks like checking the amount of a prepaid account or obtaining account details. SMS messages are often used in areas with poor internet access because they don’t require an internet connection to function.

SIM card carriers can be divided into two categories:

  1. Carriers that employ the GSM (Global System for Mobile Communications) technology: The most widely adopted mobile communications standard worldwide is GSM technology. GSM carriers include AT&T, T-Mobile, and other international companies.
  2. Carriers that utilize CDMA (Code Division Multiple Access): These companies make use of a distinct type of technology known as CDMA, which is mostly employed in the US by carriers like Verizon and Sprint.

Some carriers also provide dual-SIM cards that can be used with both GSM and CDMA networks in addition to these two primary varieties. Depending on the availability and coverage of each network, this enables the device to connect to various networks.

89012 sim card carrier and 89148 sim card carrier

Rather than being distinct carrier codes, the serial numbers 89012 and 89148 are particular to each SIM card. We all know that each SIM card is identified and tracked using its unique serial number, which is stored in the memory of the SIM card. It’s important to understand that the SIM card’s carrier is not determined by the 89012 or 89148 numbers. You need to take a look at the SIM card box. You can also check the information contained on the SIM card to determine which carrier the SIM card belongs to.

By entering a code on your phone, you can access the carrier information saved on your SIM card. For instance, you may view your SIM card information, which includes the carrier name and phone number, on the majority of GSM networks by dialing *#06#. You can also look at your phone’s settings. You can also use an internet tool that gives SIM card information to check the carrier information. The 89012 and 89148 codes merely serve as serial numbers to identify and monitor every SIM card; they do not reveal the carrier with which the SIM card is linked. You will need to check your phone’s settings, call a code, or utilize an online tool to determine which carrier you are using.
