T-Mobile E372(Huawei) is sold under the name WEB ‘N’ WALK STICK BUSINESS II and it’s SIM card free without lock in Germany version. The Dual Carrier HSPA+ Huawei E372 reaches up to 42Mbit/s (according to manufacturer). The dual cell HSPA+ could support double speed than single HSPA+ network connection.
Huawei E372 with the Netgear MBRN3000 Router – but not with T-Mobile firmware
If you Plug the Huawei E372 to the router MBRN3000, it will not be recognized. The reason is the special T-Mobile firmware. In order to be able to run the E372 stick with the Netgear MBRN3000, user need a neutral firmware. This could be obtained free of charge on the Internet.
Instructions to play the firmware(User need 2 steps to play the firmware):
- A. The current version firmware for the stick to find on dc-files.com
- B. Flash code generator for Huawei (v4mpire_unlocker, simply v4mpire_unlocker in Google search)
First, you create the Flash code v4mpire_unlocker with the program. You start this program and return the IMEI number of a stick. The IMEI number can be found in the T-Mobile Connection Manager, or lay the stick in packing. Then click on Calculate the code. Now the flashing is: Code displayed. We record this or copy it.
Then you start the firmware exe from dc-files.com. Shortly thereafter, we will post flash demand code we created before. Just enter the code and the stick gets filled with the new firmware. The whole takes a few minutes.
Now you can plug the stick into the Netgear MBRN3000 and let run through the setup wizard. The stick is found and installed.
However, we have found that with the Netgear MBRN3000 loses about 40% of performance. When HUAWEI E372 stick connects to the PC directly, the speed of up to 24Mbps can be reached, but with the Netgear MBRN3000 router, only 16 Mbps can be achieved. Apparently the Netgear MBRN3000 is not designed for Dual Carrier HSPA+ and can’t not get sufficient power for such high bandwidths.
The HUAWEI E372 stick also works with all providers in Austria because it is not locked to T-Mobile. It’s SIM card free and support 3G UMTS/DC-HSPA+ Qual-bands.
