Hello luisen, This is a guide to root the Fusion 2. I searched for about a week for a free way to preform a carrier unlock because I wanted to use T-Mobile with the Fusion 2. I was not able to find a free method, and ended up paying $20 to unlock mine. I watched this Youtube video:http://www.youtube.com/watch?v=iPKh4tg4-CU Then followed the link they provided in the description: http://www.pugetsoundelectronics.com/Unlock-Att-Huawei-Fusion-2-U8665-0070.htm How it works is you give them your IMEI and other information, pay them and you receive a confirmation e-mail for your purchase. 2-3 days later you receive an e-mail with the Unlock code, and instructions. Worked like a charm for me. **I have no association with the company, it's just how I did a carrier unlock for my phone.
