T-Mobile Hungary has launched E3372h as well as E3372s dongle. Both can be easily unlocked. For E3372s just change the SIM with another carrier and it will ask you for unlock code. Enter correct 8 digit unlock code and enjoy with any network provider SIM.

Unlocking of E3372h is slightly different as it comes with V4 algo code. You have to generate NV hash code, then unlocking is possible.

I have extracted some information from DC unlocker:

Found modem : E3372
Model : Huawei E3372h
IMEI : 866119024945116

You can see here, E3372h T-Mobile Hungary locked device has firmware version But good news is that it has un-customized firmware and there is no need to flashing the device. Other notable thing is that its dashboard version is UTPS22., means it is not a hilink data-card.
