One benefit that used to exist was changing the IMEI of an Android smartphone to that of a Blackberry device to be able to use Blackberry internet Service on Android. BlackBerry Internet Service (BIS) has since been discontinued years ago, so that benefit is gone with the wind.

How To Change IMEI Number Of Your Phone

There are people who keep asking about how to change the IMEI of their mobile phone. The first issue is that it is illegal to do so in many countries. It is easy to see why: it is a unique identifier. As such by default, you shouldn’t be wanting to change it if you are not involved in illegal activities, all other things being equal.

In the end, changing your IMEI provides no real benefits in terms of privacy or security. It actually poses a risk of killing your phone, and also opens you up to legal issues. You do not want to be caught on the wrong side of the law.

Lastly, keep the IMEI number of your device securely. Avoid putting it out in public. If you observe gadget review videos, reviewers hide the number when displaying the package of the phone or the phone itself (when a label with the number printed on it is on display).

You should not publish your IMEI (International Mobile Equipment Identity) number publicly or share it with individuals or websites that you do not trust. Your IMEI number is a unique identifier for your mobile device, and it should be treated as sensitive information.
