The Equipment Identity Register (EIR) is a database that stores the identities of all mobile devices that are registered with a cellular network. The EIR stores various information related to mobile devices, but one of the options listed is NOT stored in the EIR. Let's go through each option to determine which one is not stored in the EIR:

1. International Mobile Subscriber Identity (IMSI): The IMSI is a unique identifier assigned to each mobile subscriber and is used to identify the subscriber in the network. This information is typically stored in the EIR.

2. Mobile Equipment Identifier (MEID): The MEID is a unique identifier assigned to mobile equipment, such as smartphones or tablets. This information is also typically stored in the EIR.

3. International Mobile Equipment Identity (IMEI): The IMEI is a unique identifier assigned to each mobile device and is used to identify the device in the network. This information is typically stored in the EIR.

4. Service Provider Identifier (SPI): The SPI is an identifier that represents the service provider or network operator. While this information may be associated with the mobile device, it is not typically stored in the EIR.

5. Network Subscriber Number (NID): The NID is a number assigned to a network subscriber and is used for identification purposes. This information is typically stored in the EIR.

Based on the above analysis, the option that is NOT stored in the EIR is the Service Provider Identifier (SPI).
