Guys, if you are looking for good unlocked modem, don’t buy this one. It’s locked for Airtel operator only and other Sim-cards are not accepted. I’ve tried to use software supplied with modem and native Huawei software - both claim that my Sim-card (Megafon-Russia) is not allowed. Seller’s description says modem is fine with various networks, but this is not truth - Airtel only.
