I have already successfully unlocked Airtel-branded Huawei E5573s-606 router. We are also offering unlocked E5573 router in cheap rates. But, in case you want to lock your router again, and don’t want to further use any another network provider SIM card in E5573 then we have original firmware too.
After running this firmware (link below the post), your E5573 router will be successfully locked again as brand new. This firmware is tested with one device and working fine.
While running the firmware, the device will ask you firmware code, leave a comment below with model and IMEI to get the firmware password.
