Tweaking an IMEI isnt the same thing as changing the IMEI of a device.
In this brief guide, I'll be explaining how to tweak an IMEI so you can use it to get free data (megabytes) and other bonuses.
First, you need a base IMEI (this is the part of the IMEI that's common to all devices that qualify for the promo)
An IMEI comprises of 15 digits so when you get an eleven digit IMEI to tweak, you need to make it up to 15, and that's what this guide is about.
A tweaked IMEI consists of three parts
3. Validating digit
If for example, someone says "Tweak 86987800044" . That's just 11 digits so its considered as the Base.
You need to make it up to 14 digits by adding any three random digits. The three random digits you add are considered as the Salt. The 15th digit is the Validating digit. Its the digit that ensures that the newly created IMEI is a valid IMEI
Lets use the above Base as an example
Above, I have the 11 digit Base in green and the Salt (three random digits I added to make it 14 digits in all) in blue. What is missing is the 15th digit which is the Validating digit.
To get this last digit,
* Go to http://www.nobbi.com/imeicheck.php (or use IMEI Analyzer)
* Paste the 14 digits into the input box and click Check
* You should now have a valid 15 digit IMEI
In this example, I'll have:
Base is Green (Part thats' common to all devices that qualify)
Salt is Blue (Makes base up to 14 digits)
Validating digit is Red (Ensures we end up with a valid 15 digit IMEI)
You can then write the IMEI to the phone and send the Promo code to get the bonus.
