I had earlier written the article for unlocking of K4511 Vodafone Huawei Australian modem. In Australia, Huawei has also launched the Vodafone K3771 modem. Unlocking of Vodafone K3771 Huawei Australian modem is easy and after unlock you can use any another network provider sim on your data card. When there are so many benefits of unlocking, I want to say that freedom in network selection, then why not unlock it. After unlocking you can not only use Vodafone SIM, but you can use any network sim in the world e.g T-Mobile, Telstra, Airtel, Aircel, MTN, Glo, EE, Tre, etc.
