IMEI 1 and IMEI 2 are the International Mobile Equipment Identity numbers of a dual-SIM mobile phone. Each SIM slot has its own IMEI number. It is used by mobile network operators to track and identify mobile phones.
If your phone has two IMEI numbers, IMEI 1 is usually the IMEI number of the first SIM slot, and IMEI 2 is the IMEI number of the second SIM slot. However, this may not always be the case, so it is best to check your phone’s manual to see which IMEI number is associated with each SIM slot.
It is important to keep your IMEI number safe and secure. If you lose your phone, you can use the IMEI number to report it stolen or lost to your mobile network operator. You can also use the IMEI number to track your phone if it is lost or stolen.
