I have earlier shared details about Huawei E5377, which is available in Romania through Orange network.

Today, I have unlocked one device successfully, which was locked to Ooredoo network in Kuwait. Unlocking is the one-time job and after unlocking the device, you can use any another network provider SIM, as well as default SIM.

Currently, sub-models Huawei E5377Bs-605 and E5377s-32 are also available in various countries. Optus of Australia is also providing this device, dubbed as Huawei E5377 WiFi modem.
