Most times when i browse with my system using GLO or AIRTEL sim card, to login into any yahoo account, it will keep telling me Invalid Password when the password is valid. But when i browse with MTN or ETISALAT i will never experience that for once. Recently i subscribed to GLO network because MTN 3G is no longer working in my office area and Etisalat these days is not fast enough as before. The GLO is really BOLT speed here but please how do i solve this yahoo Invalid password problem?
