Questions about Multi-IMSI SIM Cards?

This article gives a detailed explanation about multi-IMSI SIM cards and how they work. 

Multi-Carrier SIM FAQs

A multi-carrier SIM card is a special type of SIM card that allows you to switch between different mobile network carriers without changing the physical SIM card. It offers flexibility and convenience by enabling access to multiple networks on a single SIM card.

A multi-carrier SIM card contains profiles for multiple mobile network operators. These profiles typically refer to an IMSI. When you insert the SIM card into your device, it detects the available networks and allows you to select the desired one. You can easily switch between networks through your device’s settings without needing to swap SIM cards.

IMSI stands for International Mobile Subscriber Identity. It is a unique identification number assigned to each mobile subscriber globally. The IMSI is stored on the SIM (Subscriber Identity Module) card inserted into your mobile device. It comprises three parts: the Mobile Country Code (MCC), Mobile Network Code (MNC), and Mobile Subscriber Identification Number (MSIN). Together, these components uniquely identify a mobile subscriber and facilitate their authentication and access to mobile networks. The IMSI plays a crucial role in enabling seamless communication between your device and the mobile network infrastructure.

A multi-IMSI (International Mobile Subscriber Identity) SIM card is a type of SIM card that can store multiple IMSI numbers. The IMSI is a unique identifier associated with a mobile subscriber in a GSM or UMTS network. By having multiple IMSI numbers stored on a single SIM card, a user can switch between different mobile network operators or different subscriptions within the same operator without changing the physical SIM card. This can be useful for users who travel frequently or who want to take advantage of different pricing plans or network coverage options offered by different operators.

Most unlocked GSM or LTE-compatible devices are compatible with multi-carrier SIM cards. However, it’s always a good idea to check with your device manufacturer or carrier to ensure compatibility before purchasing a multi-carrier SIM card.

No, you do not need to download any special software or apps. Selection of the desired carriers on the multi-carrier SIM card, is either done automatically based on the SIM provider’s settings, or manually selected by the SIM provider or user in a cloud-based administration portal.

With traditional SIM cards, switching carriers requires getting a new SIM and manually inserting it into your device. With SIMs like the Datablaze DB1 eUICC technology allows SIMs to store multiple profiles and enables remote SIM provisioning, so you can change carriers Over-the-Air.
