The Nokia 150 RM-1190 is a popular, budget-friendly feature phone built primarily on a MediaTek (MTK) processor or specialized feature-phone chipsets. Because it lacks a complex operating system like Android, its identity parameters—such as the 15-digit IMEI number—are hardcoded into the device's Non-Volatile Random-Access Memory (NVRAM) or firmware partition.

Depending on the specific firmware version installed on your RM-1190, technicians use the following secret codes to prompt an IMEI configuration menu: *#70003# *#0066# Standard Code Execution Method Power on the Nokia 150 without a SIM card inserted.

The International Mobile Equipment Identity (IMEI) is a unique number assigned to every mobile device. It's used by the network to identify valid devices and can be used to block stolen or lost phones.

Mobile operators and law enforcement use the IMEI to identify valid devices and block stolen or blacklisted phones from accessing cellular networks. Modifying this identifier can result in your device being permanently blocked from networks, loss of warranty, and potential legal consequences depending on your country's laws.
