Huawei E3276 LTE Category 4 USB Dongle
This model provides packet data service of up to 150/50 Mbit/s on LTE networks
Main problem that Technicians encounter when trying to use this dongle with Drive Test software such as Ascom Tems Investigation Is that they are trying to use commercial model of this usb dongle.
This will never work !
In order to get diagnostic data from dongle it has to be flashed with Hisilicon engineering firmware and also have license.
When I mentioned License I was referring to Hisilicon dongle license which needs to be loaded to dongle.
Furthermore, one will also require Hisilicon license for Tems software.
Here you can see screenshot of result when all is done as above.
