If you want to buy the phone, then you should check its validity. In the case of buying both new or old phones, it is very important to check the validity, because it lets you know that you are buying the right phone. Keep in mind, do not buy such a phone if the status of mobile validity is black listed, duplicated or already in use. You can check the validity of the phone before buying it through Know Your Mobile (KYM).
To check the validity of any phone, you need IMEI (International Mobile Equipment Identity). IMEI is a 15 digit number. IMEI number is written on the packing box of the mobile. Apart from this, it is also written on the mobile bill. If you are buying an old phone or want to know the validity of your existing phone then you have to dial * # 06 # from your phone. As soon as you dial this number from the mobile, the IMEI number will appear on the phone screen. You can know the validity of your mobile through Know Your Mobile (KYM) in 3 ways.
Via SMS: If you want to know the validity through SMS, then you have to type KYM <15 digit IMEI number> from your phone. Then this message has to be sent to 14422. After this, you will get a message related to the validity of the mobile.
With the help of the KYM app: You can also know the validity of your mobile phone through the KYM app. The KYM app is available on the Google Play Store for Android users and the App Store for iOS users.
