Aircel datacard

Now we are going to learn about how to unlock huawei datacard / dongle / modem. This is totally free. You are going to unlock by yourself without paying any single penny of yours. Some websites claiming money for this. Do not follow them. You can do by yourself without anyone help. Believe in yours. 😄

Why we need to unlock..? what is the use of that..?

If you are bought this device from any internet service provider they locked that device with particular network SIM. So you can't use any other network with this device. If you unlocked that device you can enjoy 3g with any SIM.

I bought this device e303s from Aircel in chennai for Rs.1600 - 3 month - 6GB - prepaid

What is needed to unlock..? Its hard to get one..?

Basically you need an unlock code for that. Earlier huawei modems are using different algorithm. That is easy to hack. Even some software tools available to find out the code. Now all modems follow new algorithm.

How can I found my device follows new algorithm or old algorithm..?

If you modem IMEI starts with 86** .Then that is the new algorithm. This tutorial for new algorithm modems only.

How to get the unlock code of modem..?

There are two ways to get your unlock code. Be prepared with your IMEI no of device.
