SIMLock Unlock Code Delivery Time: 10 min to 8 hrs (mostly completed within an hour)
If I have specified in the some of the posts about customized firmware, then you can make payment. You need to change the firmware, then the device can be unlocked.
Devices which are released before 2013, orders can be placed on this page.
The Huawei modems and routers which were launched after 2013, are supported under this service. Before making payment, make sure your dongle is asking for unlock code after changing the SIM card. If your device is not asking for unlock code, then before making a payment, let me know via comments.
