Like Huawei and Micromax, ZTE is also a leading company in manufacturing of modems. ZTE keeps launching modem with the help of network provider like Aircel, Airtel, Vodafone, MTS, Tata Docomo, Idea, T-Mobile, Metro PCs, etc. But, problem is that it comes locked to a particular network through which you have purchased. If you have purchased modem of Vodafone then you can not use the SIM of airtel. For using another network provider SIM you have to purchase a new modem/phone again. Hence, we keep writing the article about “how to unlock the modem with the help of firmware, dashboard, unlocking codes, custom firmware or dashboard?”.
