How to reflash the E3372 modem?

Question

mobile connection

There is a Huawei E3372h-153 modem, it eats any SIM card from the factory. But the trouble is that I need an MTS, and he bastard fires that this is a modem and does not allow you to insert a SIM card without speed limit. That is, there is a tariff line for modems, but there is a 4Mbit limit and unlimited. And I don’t need unlimited traffic, I just need speed without restrictions.
I don't even know how to ask Google. What needs to be changed in the modem so that the operator thinks, for example, that this is some kind of ordinary iPhone?

Answer 1

look for change ttl + imei must be from smartphone
