I have already written about unlocking of Huawei LTE CPE B593u-91 (B593) MOBILY Saudi Arabia. Earlier, it was available in the market with un-customized firmware, means unlocking was easy, with the only unlock code. But, new Huawei routers still carry model no. B593u-91 but Mobily has changed the UI of the device and no one is able to unlock it because there is no place to enter the unlock code.

However, unlocking can be achieved by a firmware upgrade (download link is provided at the end of the article), which is risky, however, it is tested and working with Huawei B593u-91 of Mobily carrier.
