According to me telenor doesn't seems to be a bad option to buy.Telenor has some real cheap offers which can keep up with you for the whole month but the quality and the connection is a pretty serious matter for telenor.Telenor is best for someone who talks too much on phone and want cheap affordable tariffs and uses only whatsapp and some third party browser ( uc, opera) cause you can't stream youtube on this connection smoothly.Telenor can be one of the best mobile operators if it starts to work more on the network stability and improve the connection.
Honestly, Telenor cheap offers attracts people towards it and that causes a huge traffic on its signal strenght but that should not be an excuse for any mobile operator to stop improving.So until telenor connection gains some more strenght I will rely on other mobile operators
