I bought unlock code on:

http://plati.com/asp/pay.asp?id_d=1613528

and I got something like this: cost=5$

Next I downloaded file Firmware_Huawei_E3272s-153_24.436.07.02.1202_Poland_Polkomtel_Polsat.7z from:

http://unlock4modem.in/download-huawei- ... date-free/

Firmware update wants Код для прошивки

After update my device id magically changed to 0x14db and Routerboard after restart works with LTE: I have E3272 from PLAY (P4) network
