It is often used for testing, programming, or in devices that do not need a cellular connection. The OYEITIMES 2G GSM SIM Card is a programmable SIM card that allows users to input ICCID, IMSI, PIN, PUK, ADM, KI, and COMP128 algorithms without needing a carrier’s SIM card. A <strong> without SIM card </strong> is a SIM card that is not tied to a specific mobile network provider. It is often used for testing, development, or in devices that do not require a cellular connection. These cards are typically used in scenarios where a user wants to simulate a SIM card or test a device without an active network. <dl> <dt style="font-weight:bold;"> <strong> Without SIM Card </strong> </dt> <dd> A SIM card that is not associated with a specific mobile network provider and can be programmed or used for testing purposes. </dd> <dt style="font-weight:bold;"> <strong> Programmable SIM Card </strong> </dt> <dd> A SIM card that allows users to input or modify data such as ICCID, IMSI, and other network-related information. </dd> <dt style="font-weight:bold;"> <strong> ICCID </strong> </dt> <dd> Integrated Circuit Card Identifier, a unique number used to identify a SIM card. </dd> <dt style="font-weight:bold;"> <strong> IMSI </strong> </dt> <dd> International Mobile Subscriber Identity, a unique identifier for a mobile user. </dd> <dt style="font-weight:bold;"> <strong> PIN </strong> </dt> <dd> Personal Identification Number, used to unlock a SIM card. </dd> <dt style="font-weight:bold;"> <strong> PUK </strong> </dt> <dd> Personal Unblocking Key, used to unlock a SIM card if the PIN is entered incorrectly too many times. </dd> <dt style="font-weight:bold;"> <strong> ADM </strong> </dt> <dd> Administrative Key, used for managing SIM card access and security. </dd> <dt style="font-weight:bold;"> <strong> KI </strong> </dt> <dd> Key Identifier, used in cryptographic operations for secure communication. </dd> <dt style="font-weight:bold;"> <strong> COMP128 Algorithm </strong> </dt> <dd> A cryptographic algorithm used in GSM networks for authentication and encryption. </dd> </dl> I recently purchased the OYEITIMES 2G GSM SIM Card without a SIM card, and I used it to test a new mobile device.
