Hi Forum members, Recently I bought the reliance net connect ZTE MG 880 modem for surfing the net. Unfortunately I locked the modem using the lock modem option from settings and lost the password. I tried 0000, 00000000 which didn't work. I called the rweb center and they tell to contact the main service center, they/I don't have the contact phone numbers. Can any one help me out to unlock the modem from settings using any default password. Thanks, Dinesh
