For reason alot service provider is using huawei device, some of the service provider is request huawei to special make the device with their own logo
see example below
huawei b315 maxis supplied
huawei b315 huawei supplied
At world it still have alot operator like tmobile , vodafone , digi , celcom ++
they are using huawei modem
At summary, it is excatly same model , and same hardware use for most of telco logo device vs huawei logo device.
