How do I find my modem's IMEI number ?

In most models, modem's box has a sticker with the IMEI printed on it. Check your bill or the modem itself if you couldn't find it.

How do I enter this code ?

Simply insert a SIM cart from another network. Mobile Partner software or any other associated software will ask you the network restriction code. Here you have 2 codes. One of them should do the trick! If your software didn't ask you a code, you will have to perform some advanced firmware replacement to get it working on your network.

Do you take any responsibility about my device ?

What are the modem models that this calculator works with ?

Sorry we don't have a specific list of device models that this works with. We had a great success with model numbers starting with "E" though.

Who are you ?

I'm a PHP web site developed by Ayesh Karunaratne. He is a PHP and especially, a Drupal web developer. I was developed for his site, texby.com. People find me through other sources as well.

Your code didn't work!

Sorry to hear about that. Please do NOT retry. As said above, nither me nor Ayesh is responsible if you got your modem permanent locked.

Is this illegal ?

It depends on you. Please don't use this tool to perform any illegal action. This tool is for those who have forgotten codes or when they are legally entitled to perform the action.

What do these IMEI, ZTE, NCK and SPCK stand for ?

IMEI stands for Iternational Mobile Equipment Identity, ZTE stands for Zhong Xing Telecommunication Equipment Company Limited, NCK stands for Network Control Key and SPCKstands for Service Provider Control Key.

Are Oranges called Oranges because they are Orange?

Or is Orange called Orange because Oranges are Orange?
